It is possible to input a character (custom character) defined in a limited character code system(s) among a plurality of existing character code systems in other character code system. A character code input support system includes: a step of searching an undefined character code DB to identify a character code having used/unused information indicating the unused state among character codes correlated with character code system identification information excluding inputted character code system identification information; a step of reading the identified character code and character code system identification information correlated with the character code from the undefined character code DB; a step of modifying the content of the character code used/unused information correlated with the character code which has been read out, to the used state and storing it in the undefined character code DB; and a step of storing the inputted character code system identification information and the character code correlated together with the read-out character code system identification information and the character code in a text DB while correlating them with arbitrary character management information.

Description

 Specification

 Character code input support system, character code input support program

 [0001] The present invention is a computer for inputting or displaying characters (external characters) defined only in some character code systems when there are a plurality of character code systems such as JIS standards. It is about the system.

 Background art

 [0002] Characters defined in standardized character code systems such as the JIS standard are usually not supported by a single professional software, and may be subject to input / output computer processing. Can not. However, the system user assigns a character design to a character code that is not defined in the standardized character code system and defines it, so that characters that are not in the standardized character code system can be input / output by computer processing. Can be the target of.

 [0003] For example, even in JISX0208, which is a standard generally used as a Japanese character code, a communication carrier or a hardware manufacturer uses a “machine dependent character” or “vendor specific character” in an undefined area of the character code. Often a character called "" is defined. These “model-dependent characters” or “vendor-specific characters” have problems in terms of compatibility because they cannot be input or output on a computer of another company other than the company that defined the characters. .

[0004] In addition, even in a mobile phone that is a small computer, an undefined area of the character code system of each communication carrier is used to display a specific picture in an area of one character called an "pictogram". Special characters are defined. Examples of pictures displayed by these “emojis” include various things such as human faces, animals, food, plants, shops, and national flags. However, these `` pictograms '' are arbitrarily assigned by each communication carrier (mobile phone company) to an undefined area of a standard character code system such as JISX0208. There is no sex. Therefore, even if an e-mail containing the “Emoji” character code entered on the mobile phone of communication carrier A is sent to the mobile phone of communication carrier B, the mobile phone of communication carrier B In the story, the “pictogram” cannot be displayed correctly, and the so-called “garbage” phenomenon occurs. Therefore, the “pictograms” uniquely defined by each communication carrier cannot be used for communication between mobile phones in the network within each communication carrier. In other words, each communication carrier uses a unique character code system that includes a standard character code system such as JISX0208 and defines a unique “pictogram” in the undefined area of the character code in the character code system. It is doing.

 [0005] On the other hand, for content providers who distribute various contents by e-mail etc. to mobile phones that are small computers, pictograms that can be displayed colorfully with data of one character (2 bytes in JISX0208) Used, and! /, U needs are strong! However, as mentioned above, special characters such as “pictograms” are not compatible between communication carriers, so the content provider must create content data to be distributed for each communication carrier. Will be hard.

 [0006] The following documents exist as prior documents related to the present technology.

 Patent Document 1: Japanese Patent Laid-Open No. 2004-96454

 Patent Document 2: JP 2004-240550 A

 Patent Document 3: Japanese Patent Application Laid-Open No. 2004-295344

 Disclosure of the invention

 Problems to be solved by the invention

[0007] (1) As a prior art for solving this inconvenience, there is a method of performing mutual conversion of character codes of “pictograms” defined between communication carriers. For example, if a pictograph of “smile” in communication carrier A is converted to a smiley character in communication carrier B! /, A correspondence table of character codes of pictographs in each communication carrier is created. As a result, even if an e-mail containing pictograms is sent to a mobile phone of a communication carrier (destination communication carrier) different from the mobile phone communication carrier used for sending e-mails, Although the design is different, it can be converted into pictograms that are common in concept. In other words, according to the correspondence table of pictogram character codes in each communication carrier, when sending an email, the pictogram character code of the source communication carrier of the email is converted to the pictogram character code of the destination communication carrier. . [0008] However, the method of creating a correspondence table of pictogram character codes in each communication carrier is only to convert them to similar pictograms, and is the same for mobile phones belonging to any communication carrier. The content of the design has been distributed, and it cannot meet the needs of content providers. Also, when mutual conversion is made to similar pictograms, the impression quality of the entire content by the converted pictograms may be changed to content with an impression quite different from the design originally created by the content provider. There is. Furthermore, in the case of mutual conversion to similar pictograms, there is an inconvenience that if the pictogram corresponding to the pictograph of the transmission source communication carrier does not exist in the pictograph of the transmission destination communication carrier, the conversion itself cannot be performed.

 [0009] (2) In addition, as another conventional technique, in a personal computer connected to the Internet, an e-mail including a pictograph of a communication carrier can be input and created for transmission to a mobile phone. Support software exists.

 [0010] However, since such pictogram input support software can only support the character code system of one specific company, only the pictograms of one communication carrier can be input and used. The user must choose whether to enter ... In addition, the pictograph data that has been input is stored in the support software in the form of html tag data (for example, <IMG SRC = 0351.gif »or any combination of multiple characters (for example, I 003 I)). For this reason, when the html tag data or a combination of multiple characters is entered, the support software recognizes that the user is instructed to enter a specific pictograph even if the user does not intend to enter the pictograph. As a result, tml tag data and combinations of multiple characters can cause unexpected characters to be lost in pictograms.

[0011] For example, under the support software that adopts the rule that “html tag data of IMG SRC = 0351.gif> represents a specific pictogram”, the original “0351. The command “Display file gif” cannot be executed. Similarly, under the support software that adopts the rule that “character string I 003 I represents a specific pictogram”, the original instruction “display character string I 003 I” may be issued. become unable. Means for solving the problem

 [0012] Therefore, in order to solve the above problem, a character code input support system according to the present invention includes a storage unit that stores information, a processing unit that processes information, and an input unit that receives a command from a user. In order to input characters (external characters) that are defined only in some of the character code systems, among other character code systems, in other character code systems. This is a character code input support system.

 [0013] Further, the storage means of the character code input support system includes a character code system identification information for identifying the character code system, a character code, and a character representing whether or not a character code having an undefined character is used. An undefined character code DB for storing the code usage information in association with each other, a character management information for managing the input character, the character code system identification information, and a sentence DB for storing the character code in association with each other. I remember it.

 [0014] Then, the processing means of the character code input support system (1) receives the input of the character code system identification information and the character code as a character input command via the input means, (2) Character code body other than the entered character code system identification information Among the character codes associated with the system identification information, the character code used or not associated with the character code that is not used The undefined character code DB of the storage means is searched and specified, and the specified character code and the character code system identification information associated with the character code are read from the undefined character code DB of the storage means. At the same time, the content of the character code usage information associated with the read character code is changed to information indicating that it is in use and stored in the undefined character code DB of the storage means. (3) The character code system identification information and character code input from the input means and the read character code system identification information and character code are associated with any of the character management information, and the storage means It is characterized by memorizing in the sentence DB.

Here, the “storage means” corresponds to a storage device in a computer system such as RAM, ROM, HDD or the like. The “processing means” corresponds to, for example, an arithmetic device in a computer system such as a CPU or a central processing server computer in a computer system connected by a communication network. “Input means” means, for example, an input device in a computer system such as a keyboard, a mouse, and a touch panel, or a communication network. This includes mobile phone terminals and personal computers as information terminals in connected computer systems. This “character code input support system” may be configured in one piece of hardware such as a personal computer. In a computer system connected via a communication network, the “processing means” A plurality of computers such as a central processing server computer, “storage means” is a storage device managed by the central processing server computer, and “input means” is an information terminal (mobile phone, personal computer) that communicates with the central processing server computer. It may be configured by.

 [0016] Examples of the "character code system" include various character codes such as JIS code standard, ASCII code standard, Unicode standard, ISO code standard, original character code standard of communication carrier and nodeware manufacturer, etc. There is a system. “Character code” means individual character codes constituting the character code system. “Character” in “Character code” is a “character” in a broad sense, and includes special symbols, pictograms, punctuation marks and symbols, blank characters, line feed characters, and the like. If the character code system has 1 byte as 1 character, 256 character codes can be used, so a maximum of 256 characters can be defined. Similarly, if the character code system has two bytes as one character, 65536 character codes can be used, so a maximum of 65536 characters can be defined.

 [0017] "External character" is a character that is defined only in a part of a plurality of character code systems, and is not defined in an undefined character code system. Characters that cause problems such as profits. An example of an external character is a character that expresses a specific picture, called an “pictogram”, uniquely defined by a mobile phone carrier.

[0018] "Character code usage information" means that a character is defined in each character code system and V is undefined, and an undefined character code is defined in the character code system. This is information indicating whether or not external characters of other character code systems are assigned. “Character management information” is management information of character data for one character in text data, and is the smallest unit that a user of a character code input support system can command to input or delete. “Arbitrary character management information” means that the “character management information” itself is convenient management information for character data for one character in the text data, so when an instruction to input a new character is received, For example, in a system designer's arbitrary method such as serial numbering It means good. In other words, any numbering method for character management information can be used as long as it can manage the order of character data in text data.

 In addition, the “undefined character code DB” stores any undefined character code in any character code system by storing the character code system identification information, the character code, and the character code usage information in association with each other. Can be specified as unused or in use. The “text DB” specifies the text data as a set of character codes by specifying the character code system identification information by associating and storing the character management information, the character code system identification information, and the character code. Can do. In the present invention, the meaning of “association of information” is not necessarily stored in one logical record to be associated, but there is one DB such as “undefined character code DB” or “text DB”. The above DB power may be configured. For example, there is DB1 that stores the association between character code system identification information and DB identification code, and DB2 that exists for each DB identification code and stores association between character code and character code usage information. Then. In this case, the association between the character code system identification information and the character code and character code usage information

Therefore, the DB1 and DB2 correspond to the “undefined character code DB” in the present invention. In other words, the “association of information” in the “undefined character code DB” and the “text DB” only needs to be able to specify the information to be obtained by “association of information”. The same applies to other DBs other than “Undefined character code DB” and “Text DB”.

 [0020] "Character input instruction" is information for instructing input of a character, and includes information (character code system identification information and character code) of which character code system and which character is input. In addition, the “character input command” does not necessarily input only one character of data, but may input a plurality of characters. In this case, a plurality of “character code system identification information and character code” are specified. Including!

 [0021] The above definitions also apply to the following inventions.

When the present invention is used, for the character code system represented by the character code system identification information input from the input unit, the input character code system identification information and the character code are stored in association with the character management information. Is stored in the DB. On the other hand, the entered sentence For character code systems other than the character code system represented by the character code system identification information, character codes that are not used in the character code system are stored in the text DB of the storage means in association with the character management information. As a result, even if the user is not particularly conscious, while using the undefined character codes that are not used in the character code system effectively, while avoiding unexpected character loss, Matching character codes can be entered. When the user specifies specific character code system identification information after completing the text input task, the text data as a set of character code data that matches the specified character code system can Obtainable.

 [0023] 2. A character code input support system according to another invention includes a storage means for storing information, a processing means for processing information, and an input means for receiving a command from a user. This is a system that is defined only for some of the multiple character code systems, and for inputting characters (external characters) into other character code systems. It is a code input support system.

 [0024] Further, the storage means of the character code input support system includes a character code system identification information for identifying the character code system, a character code, and a character indicating whether or not a character code having an undefined character is used. Information to display undefined character code DB, character code system identification information, character code, and character codes defined in the character code system and external characters! An external character display DB for storing the external character display information in association with each other, a character management information for managing the input character, the character code system identification information, and a sentence DB for storing the character code in association with each other. I remember it.

[0025] Then, the processing means of the character code input support system (1) accepts the input of the character code system identification information and the character code as a character input command via the input means, (2) Character code body other than the entered character code system identification information Among the character codes associated with the system identification information, the character code used or not associated with the character code that is not used The undefined character code DB of the storage means is searched and specified, and the specified character code and the character code system identification information associated with the character code are read from the undefined character code DB of the storage means. In addition, the contents of the character code use / non-use information associated with the read character code are displayed. Changing the information to indicate that it is in use and storing it in the undefined character code DB of the storage means; (3) external character display information associated with the input character code system identification information and the character code; Searching and specifying from the external character display DB of the storage means, and reading the specified external character display information from the external character display DB of the storage means; (4) character code system identification information and character code input from the input means And the read character code system identification information and character code and the read external character display information are associated with arbitrary character management information and stored in the sentence DB of the storage means. .

 Here, “external character display information” is information for displaying an external character, which is defined in each character code system, for example, a solid font including a dot font and an outline font. For example, font information such as or picture (bitmap) data. In addition, the “External Character Display DB” stores character code system identification information, character code, and external character display information in association with each other so that a character represented by a specific character code in a specific character code system can be specified. In other character code systems in which the character is not defined, it is possible to specify external character display information for displaying the character.

 [0027] The above definitions also apply to the following inventions.

[0028] By using the present invention, for the character code system represented by the character code system identification information input from the input unit, the input character code system identification information and the character code are associated with the character management information and stored in the storage unit. Is stored in the DB. On the other hand, for character code systems other than the character code system represented by the input character code system identification information, unused character codes in the character code system are associated with the character management information in the text DB of the storage means. Remembered. As a result, even if the user is not particularly conscious, while using the undefined character codes that are not used in the character code system effectively, while avoiding unexpected character loss, Matching character codes can be entered. Furthermore, because it is possible to store the external character display information in association with character codes that are not used in the character code system and store them in the sentence DB, even if the character code system does not define a specific external character, the external character is displayed. To be able to. As a result, by using the present invention, an external character used in a plurality of character code systems is converted into a sentence. Users can input text data without being particularly aware of the character code system, and can acquire text data that can display the same content in any character code system.

 [0029] Therefore, from the viewpoint of a content provider or the like, the input means can select and input an external character in a plurality of character code systems without being particularly conscious, and can be input to any character code system computer. It is possible to create content data (text data) that can display the same content. This has a remarkable effect that is different from the effect of the conventional software that can only input text using characters defined in a specific character code system.

 [0030] 3. Further, there are a plurality of character code input support systems according to other inventions, each of which includes a processing means for processing information and an input means for receiving a user power command. It is a character code input support system for inputting V, na, and characters (external characters) that are defined only in some character code systems, even in other character code systems.

 [0031] Further, the storage means of the character code input support system includes a character code system identification information for identifying the character code system, a character code, and a character indicating whether or not a character code having an undefined character is used. Undefined character code DB that stores code usage information in association with

 [0032] The character management information for managing the input characters, the character code system identification information, and the text DB for storing the character codes in association with each other are stored.

 [0033] Then, the processing means of the character code input support system (1) receives the input of the character code system identification information and the character code as a character input command via the input means, (2) When the input character code system identification information and the character management information associated with the character code exist in the text DB of the storage means, and whether or not they exist as a result of the search Is associated with the character code system identification information and the character code associated with the character management information and newly associated with the character management information, and is stored in the text DB of the storage means, and exists as a result of the search. If not, the following (3) and (4) are performed.

[0034] Here, the processing means of the character code input support system performs "(3) and (4) The processing means (3) Among the character codes associated with the character code system identification information other than the character code system identification information input through the input means, the associated character code use / non-use information is not yet present. A character code representing use is searched and specified from the undefined character code DB of the storage means, and the specified character code and character code system identification information associated with the character code are stored in the storage means. Is read from the undefined character code DB, and the content of the character code use information associated with the read character code is changed to information indicating that it is in use and stored in the undefined character code DB of the storage means. (4) Character code system identification information and character code input from the input means, and the read character code system identification information and character code are arbitrarily set In association with the character management information, it is stored in the text DB of the storage unit, Ru der.

 The “new arbitrary character management information” is different from “the character management information associated with the input character code system identification information and character code! It means “character management information”. In other words, a new “arbitrary character management information” different from “the character management information associated with the input character code system identification information and character code” existing in the text DB is assigned a number. Then it is meaning.

[0036] The above definitions also apply to the following inventions.

[0037] When the present invention is used, for the character code system represented by the character code system identification information input from the input unit, the input character code system identification information and the character code are stored in association with the character management information. Is stored in the DB. On the other hand, for character code systems other than the character code system represented by the input character code system identification information, unused character codes in the character code system are associated with the character management information in the text DB of the storage means. Remembered. In particular, in the present invention, when an external character input command that is not defined in the character code system is made, the text DB is searched for whether the same external character was previously input and already exists in the text DB. Judgment. As a result, when the text DB already exists, the undefined character code that is already used is utilized without newly using the undefined character code that is not used. Therefore, undefined character codes that are finite resources can be used more effectively. [0038] 4. Further, there are a plurality of character code input support systems according to other inventions, each of which includes a processing means for processing information and an input means for receiving a user power command. It is a character code input support system for inputting V, na, and characters (external characters) that are defined only in some character code systems, even in other character code systems.

 [0039] Further, the storage means of the character code input support system includes: a character DB that stores character management information, character code system identification information, and a character code in association with each other; A character code conversion table DB for storing a character code conversion table in which a plurality of associations between character code system identification information and character codes are associated is stored.

 [0040] Then, the processing means of the character code input support system (1) accepts the input of the character code system identification information and the character code as a character input command via the input means, (2) A search is made as to whether the association between the input character code system identification information and the character code exists in the character code conversion table DB of the storage means. The association between the character code system identification information and the character code is identified from the character code conversion table DB of the storage means, and the identified character code is identified. The association between the system identification information and the character code, and the association between the character code system identification information input from the input means and the character code are set as arbitrary character management information. It is characterized by being stored in the sentence DB of the storage means in association.

 Here, the “character code conversion table” is a table in which a plurality of associations between character code system identification information and character codes are associated, and one association between the character code system identification information and the character code is specified. For example, the association between the character code system identification information and the character code can be specified.

 [0042] The above definitions also apply to the following inventions.

[0043] When the present invention is used, when an external character input command that is not defined in the character code system is issued, whether or not there is an external character of the same type in another character code system is determined. Search for and determine. As a result, other character code systems If there is an external character of the same type, an undefined character code, which is a finite resource, can be used more effectively by a character code conversion process that newly uses an unused character code. It is.

 [0044] 5. In a character code input support system according to another invention, in addition to the processing, the processing means further includes (5) input of the character management information as a character deletion command. (6) Character code system identification information and character codes associated with the input character management information are identified by searching the text DB of the storage means, and the identified character code The system identification information and the character code use / non-use information associated with the character code are specified by searching the undefined character code DB of the storage means and the content of the specified use / non-use information indicates non-use. Changing to information and storing it in the undefined character code DB of the storage means, (7) associating the identified character code system identification information and character code with the input character management information, It is deleted from the text DB of the serial memory means, and said.

 The “character deletion command” is information for instructing deletion of characters, and includes information (character management information) indicating which characters in the text DB of the storage means are to be deleted. In addition, the “character deletion command” may instruct the deletion of a plurality of characters, not necessarily a deletion command for only one character of data, and in this case, a plurality of “character management information” is included! / Speak.

 [0046] The above definitions also apply to the following inventions.

 Using the present invention, when the character management information as a character deletion command is input, the character code system identification information and the character code associated with the input character management information are specified. The character code in the character code system is stored in the undefined character code DB of the storage means as unused. Therefore, among the character code system identification information and character codes stored in the undefined character code DB of the storage means, those that are no longer used in the text DB of the storage means are used as unused character codes. It can be reused. As a result, undefined character codes that are finite resources can be used more effectively.

[0048] 6. In a character code input support system according to another invention, in addition to the processing, the processing means further includes (5) input of the character management information as a character deletion command. (6) Identify the character code system identification information and character code associated with the input character management information, and associate with the identified character code system identification information and character code. It is searched whether or not other character management information exists in the sentence DB of the storage means, and if it does not exist as a result of the search, it is associated with the specified character code system identification information and character code. The character code use presence / absence information is searched and specified from the undefined character code DB of the storage means, and the content of the specified use presence / absence information is changed to information indicating unused, and the storage means (7) The association between the specified character code system identification information and character code and the input character management information is stored in the text D of the storage means. It is deleted from B.

Using the present invention, when the character management information is input as a character deletion command, the character code system identification information and the character code associated with the input character management information are stored in the memory. The text of the means is searched to see if it is used in other character management information in the DB. If it is used as a result of the search, the association with the input character management information is deleted from the text DB while maintaining the association between the other character management information and the character code system identification information and the character code. Therefore, among the character code system identification information and character codes stored in the undefined character code DB of the storage means, those that are not used at all in the text DB of the storage means are used as unused codes. It can be reused.

 [0050] 7. A character code input support system according to another invention includes a storage means for storing information, a processing means for processing information, an input means for receiving a command from a user, an external system, A computer system having communication means for communication, and is defined only in some character code systems among a plurality of character code systems, and characters (external characters) can be used in other character code systems. This is a character code input support system for input.

[0051] Further, the storage means of the character code input support system is defined in character management information for managing an input character, the character code system identification information, a character code, and a character code system, It is related to the external character display information that is information for displaying external characters. The sentence DB to be added and stored is stored.

[0052] Then, the processing means of the character code input support system (1) receives the input of the character code system identification information as a sentence transmission command via the input means, (2) The character code associated with the input character code system identification information and the external character display information are searched and specified from the text DB of the storage means for each character management information, and the specified character code and The external character display information is read from the text DB of the storage means, and sent as text data to the external system via the communication means.

 Here, “external system” means that the computer is different from the processing means of the character code input support system. For example, an input means that accepts a command of user power is used. At the same time, it may be an external system. That is, the case where a text transmission command is transmitted to the processing means of the character code input support system and the text data is received from the processing means of the character code input support system is also applicable. In addition, “communication means for communicating with an external system” corresponds to, for example, hardware that serves as an interface with a communication network such as a NIC.

When the present invention is used, a character code that matches the character code system represented by the input character code system identification information and the external character display information can be acquired as text data from the text DB representing the text of the same content. The user can send the same text to an external system with a different character code system without the user being aware of the multiple character code systems.

 [0055] 8, In the character code input support system according to another invention, the sentence DB associates the character management information with a character code for a character code system represented by specific character code system identification information. Sentence DB1 that stores the character code correspondence table that associates multiple associations between the character code system identification information and the character code.

B2 is configured to store the character management information, the character code system identification information, and the character code in association with each other.

By using the present invention, it is possible to reduce the storage capacity of the storage means and to easily obtain the character code for the character code system represented by the specific character code system identification information. For example, the text DB1 stores the character codes for the character code system defined by Company A in association with the character management information, and the text DB2 stores the character code systems of Company A, Company B, and Organization C. Assume that a character code correspondence table in which all character codes are associated is stored. In this case, the association of information between sentence DB1 and sentence DB2 is made by the character code of company A in sentence DB1 and the character code of company A in sentence DB2. And since text DB1 only stores the character codes of only company A, and text DB2 can eliminate duplication of character codes for the character code systems of company A, company B, and organization C. The storage capacity of the storage means can be reduced. Also, in this example, when a text data request command is issued for the character code system specified by Company A, it is immediately collected from the text DB1 as a set of character code data in accordance with the character code system specified by Company A. Can be obtained.

[0057] 9. A character code input support program according to another invention is characterized in that, in the character code input support system, the processing means performs the processing performed by the processing means.

 The invention's effect

 As described above, when the present invention is used, for the character code system represented by the character code system identification information input from the input means, the input character code system identification information and the character code are included in the character management information. It is associated and stored in the text DB of the storage means. On the other hand, for character code systems other than the character code system represented by the input character code system identification information, unused character codes in the character code system are stored in the text DB of the storage means in association with the character management information. Is done. As a result, even if the user is not particularly conscious, the character code system can effectively utilize undefined character codes that are unused and prevent unexpected character blurring. Character code that matches the code system can be entered. When the user specifies specific character code system identification information after completing the text input operation, the text DB power is obtained as a set of character code data that matches the specified character code system. Can do.

 BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. [0060] 1. Regarding the configuration of the present invention

 (1) FIG. 1 is an overall configuration diagram of a character code input support system according to the present invention. As shown in the figure, the character code input support system according to the present invention includes an input means (11-13) such as a portable information terminal or a personal computer, a processing means 20 as a central processing server, and the central processing. The storage means 30 is a storage device such as an HDD managed by the server. The input means (11-13) such as a portable information terminal or a personal computer and the processing means 20 as a central processing server are connected via a communication line such as a communication network or the Internet.

 The character code input support system according to the present invention can be executed only by a local computer system (character code input work or the like). However, when multiple computers are configured as shown in Fig. 1, various information terminal capabilities such as personal digital assistants and personal computers with different character code systems are also used for character code input work and text. Data can be browsed.

 [0063] The components in FIG. 1 will be described in further detail. Input means 11 is a mobile phone as a portable information terminal, and a mobile phone that employs the character code system of company A, which is a communication company. The input means 12 is a mobile phone as a portable information terminal, and is a mobile phone adopting the character code system of company B, which is a communication company. The input means 13 is a personal computer as an information terminal and adopts a character code system defined for a personal computer by a standardization organization C.

 [0064] When the input means 11 which is a mobile phone of company A communicates with the processing means 20 as a central processing server, a communication network unique to company A that is a communication company, a communication server of company A, and a wide area Over a typical communication network. In other words, when the input device 11, which is a mobile phone of Company A, communicates with a communication network other than Company A, it is performed via the server (communication server) of Company A. The case where the input means 12 which is a mobile phone of company B communicates with the processing means 20 as a central processing server is the same as the input means 11 which is a mobile phone of company A. In addition, when the input means 13 which is a personal computer communicates with the processing means 20 as a central processing server, it is performed via the Internet which is a wide area communication network.

5o [0065] The input means 11, which is a mobile phone of company A, cannot normally input characters and characters that are adopted by the character code system of company A. However, since the character code input support program (client version) according to the present invention is installed in the input means 11 which is a mobile phone of Company A, the characters (not used in Company A's character code system) For example, an external character of another company can be input and a character input command can be transmitted to the processing means 20 as a central processing server. Similarly, the character code input support program (client version) according to the present invention is installed in the input means 12 which is a mobile phone of company B and the input means 13 which is a personal computer.

 (2) Next, based on FIG. 2, various information stored in the storage means 30 that is a storage device such as an HDD managed by the central processing server as the processing means 20 in FIG. 1 will be described. To do. The storage means 30 includes a common character code DB31, an external character display DB32, an undefined character code DB33, a character code conversion table DB34, a sentence DB35, and a character code input support program 36 (server version). It memorizes in the form of

 [0067] Then, the central processing server as the processing unit 20 reads each piece of information (31 to 36) stored in the storage unit 30 into the memory, and interprets and executes the program and data. Further, the character code input processing according to the present invention is performed by interpreting and executing the OS stored in the central processing server power storage means 30 as the processing means 20 and the character code input support program 36. is there.

 (3) Next, the data structure of each piece of information (31 to 35) stored in the storage means 30 that is a storage device will be described with reference to FIGS.

[0069] "Common character code DB31" illustrated in FIG. 3 associates a character defined in common in all character code systems among a plurality of character code systems and the character code of the character. This is the DB to store. In Fig. 1, it was explained that there are three types of character code systems (Company A, Company B, and C organization) as an example, but here, the characters defined in common to these three types of character code systems and the corresponding The character code of the common character can be specified. The “common character code DB31” shown in Fig. 3 has a “character code” of “1” for the “character” of “A” and a “character code” of “2” for the “character” of “B”. However, the character “C” is “3” t, the character code is “4”, and the character character “@” is “4”. It is related.

 [0070] “External character display DB32” shown in FIG. 4 is a character code system identification information that identifies a character code system, a character code, and an external character that is information for displaying an external character that is not defined in the character code system. A database that stores display information in association with it. For example, if the character code system is specified from the above three types of character code systems (Company A, Company B, and C organization), the external character code defined in the character code system and the external character are displayed. Can be specified. In the “External character display DB32” shown in Fig. 4, “Character code system identification information” representing “Company character code system”, “Character code” “50” and “Vector data Al” t, “External character display” Association with “information”, association with “70” t, “character code” and “external character display information” “vector data A2”, etc. are associated. As a result, it is possible to specify that the external character of the “character code” of “50” existing in the character code system of Company A can be displayed in other character code systems using “beta data Al”. . The “external character display information” may be picture (bitmap) data or the like using only font information such as vector fonts including dot fonts and outline fonts.

 [0071] "Undefined character code DB33" illustrated in FIG. 5 includes character code system identification information, character code, and character code usage information indicating whether or not a character code with an undefined character is used. It is a database to store in association. For example, if a character code system is identified from the above three types of character code systems (Company A, Company B, and C organization), a character code that is not defined in the character code system and a character code Character code usage information can be specified. In “Undefined character code DB33” shown in Figure 5, “Character code system identification information” representing “Company A's character code system” includes “character code” of “100” and “in use”. Associated with the “character code use / non-use information”, “200” t, “character code” and “unused” “character code use / non-use information”, and the like. As a result, “100” t and “Character code”, which are present in the character encoding system of Company A and whose character is undefined, are assigned external characters existing in other character encoding systems. Can be identified as “medium”.

[0072] "Character code conversion table DB34" illustrated in FIG. This DB stores a character code conversion table that associates multiple character code associations. For example, it is possible to specify the correspondence between similar external characters for the three types of character code systems (Company A, Company B, and Organization C). In the “Character code conversion table DB34” shown in Fig. 6, the “Character code of Company A” “410” is replaced by “490”, “Character code of Company B” and “430” t. It is related to “Character code of C organization”. As a result, the “character code” of the external character “410” existing in the character code system of Company A is “490” t in the character code system of Company B. It is possible to specify “430” t existing in the character code system, and “t” corresponding to the “character code” of the U character.

 [0073] The "text DB35" illustrated in FIG. 7 stores character management information, character code system identification information, and character codes in association with the input means of the character code input support system. It is DB to do. In Figure 7, “Text DB35” is the text management information and “Text DB1 (35a)” that stores the association between the character code for the character code system represented by the specific character code system identification information. It consists of “text DB2 (35b)” that stores a character code correspondence table that associates multiple associations between system identification information and character codes. In other words, “text DB1 (35a)” stores character codes that match the character code system of Company A in association with the character management information, and “text DB2 (35b)” stores “text DB1 (35a) ) ”Is stored, and the association when converting the character code that matches the character code system of Company A to the character code that matches the character code system of Company B or C organization is stored. For example, Company A's character code for the third character shown in Figure 7 (character management information is “3”) is “50”, and the corresponding character code for Company B is “250”. It can be specified that the code is “50”. In this way, by storing text data separately for “text DBl (35a)” and “text DB2 (35b)”, the storage capacity of the storage means 30 can be reduced, and a specific character code system identification can be made. It is easy to obtain the character code for the character code system represented by the information.

 [0074] 2. Flow of the present invention

[0075] Next, an operation flow of processing in which the central processing server, which is the processing means 20 of the character code input support system, interprets and executes the character code input support program 36 according to the present invention will be described. Hereafter, character input processing, character deletion processing, and character data transmission processing 3 One process will be described with reference to FIGS. 3 to 10 and FIGS.

(1 1) FIG. 8 is performed by the central processing server which is the processing means 20 of the character code input support system when the character input is made from the input means (11 to 13) of the character code input support system. It is a flowchart showing a character input process. First, the user of the input means inputs characters to the input means (11 to 13) of the character code input support system to create text data. Specifically, the user of the input means (11, 12), which is a mobile phone as a mobile information terminal, creates text data using the input button of the mobile phone, or uses a personal computer as an information terminal. User power of a certain input means (13) This corresponds to creating text data using a mouse or keyboard of a personal computer.

[0077] As described above, the character code input support program (client version) according to the present invention is installed in these input means (11-13). This character code input support program (client version) is a kind of editor program, and adopts, for example, the one shown in FIG. 14 as an interface for character input. As shown in the figure, the text input interface of the editor program consists of a “text data creation area” and an “external character selection area”. Characters defined in common in any of the character encoding systems of Company A, Company B, and Organization C are entered directly into the `` text data creation area '', and Company A, Company B For external characters that are ヽ characters that are defined only in some character code systems of the C organization, the “external character selection area” force is also selected and input. In the figure, it is possible to select and input an external character in any of the character code systems of Company A, Company B, and Organization C from the “External character selection area”. The text data that can be created now is displayed in the “text data creation area”.

[0078] Here, the character code input support program (client version) according to the present invention is different from a normal editor program in that an external character in a plurality of character code systems is selected and input from the "external character selection area". It can be done. Since external characters in multiple character code systems do not take into account consistency between them, different external characters may be defined for the same character code. For example, the character power represented by the character code “1100” differs between Company A and Company B. Therefore, when an external character is selected and input from the “External character selection area” in the interface of the character code input support program (client version), the character code The input means (11-13) of the code input support system stores the character code system identification information and the character code in association with each other as information about one character. For example, when an external character of company B is selected and input from the “External character selection area”, the character code system identification information indicating the character code system of company B and the character code defined for the external character of company B are displayed. Associating and storing internally. When characters defined in common in multiple character code systems are directly entered in the "text data creation area" in the interface of the character code input support program (client version), input is performed. The character code system used by the input means (11-13) is stored internally in association with the character code system identification information and the character code. As described above, the character code input support program (client version) according to the present invention can perform the same processing as a normal editor program, except that it is possible to select and input an external character in a plurality of character code systems. it can.

 [0079] (1 2) Subsequently, when the creation of the text data is completed by the input means (11-13) of the character code input support system, the user sends the created text data from the input means (11-13) to the text. An instruction is given to the input means (11-13) to be transmitted to the central processing server as the processing means 20 of the character code input support system. Then, the input means (11-13) of the character code input support system transmits the created text data and performs central processing as the processing means 20 of the character code input support system via a communication network or the Internet. Sarno receives text data as a character input command (S801). As described above, the text data transmitted by the input means (11 to 13) is composed of one character's worth of data that is associated with the character code system identification information and the character code. As a result, it is possible to specify which character code in which character code system represents the data for one character, and by having multiple associations between character code system identification information and character codes, This is text data with multiple character skills.

(13) Then, the central processing server as the processing means 20 performs character input processing on the received text data for each character data. First, the central processing server as the processing means 20 determines whether or not the character code included in the current character data to be processed in the received text data is a common character code (S802). Ingredients Specifically, as shown in FIG. 3, the common character code DB31 stored in the storage means 30 managed by the central processing server as the processing means 20 is included in the current character data to be processed. Judgment is made based on whether a character code exists. For example, if the character code included in the current character data to be processed is “3”, the character code (“C” of “3” is stored in the storage means 30 and stored in the common character code DB31. ")"), It is determined that it is a common character code.

[0081] (1-4) Then, in S802, when it is determined that the character code included in the current character data to be processed is a common character code, the central processing server as the processing means 20 Then, the character code included in the current character data to be processed is associated with arbitrary character management information and stored in the sentence DB1 (35a) of the storage means 30 as shown in FIG. 7 (S803). In other words, the current character data to be processed is composed of an association between the character code system identification information and the character code, and the character code is the same in any character code system as long as it is a common character code. This is because only the character code is stored in association with the arbitrary character management information regardless of the character code system identification information. With this S803, the processing for the current character data to be processed (data for one character) is completed, and the central processing server as the processing means 20 receives the next character data for the sentence data received earlier. If it exists, S802 is processed. In other words, the current character data to be processed is changed to the next one character data (association between character code system identification information and character code), and the processing from S802 is performed again. If the last one character of the text data received earlier is processed, the character input process ends.

[0082] (1-5) Also, in the previous S802, if it is determined that the character code included in the current character data to be processed is not the common character code, The processing server determines whether or not the association between the character code system identification information and the character code included in the current character data to be processed exists in the sentence DB2 (35b) of the storage means 30 (S804). Specifically, the sentence DB2 (35b) stored in the storage means 30 as shown in FIG. 7 contains the character code system identification information and the character code included in the current character data to be processed. Judgment is based on whether or not there is an association. For example, the current location If the character data to be processed includes the association between the character code system identification information representing “Company B character code” and the character code representing “250”, the character to be processed is stored in the storage means 30. Judge that it already exists in the sentence DB2 (35b).

 [0083] The association between the character code system identification information contained in the current character data to be processed and the character code. If it exists in the sentence DB2 (35b) of the storage means 30, the character data to be processed now The included character code is an external character code that is not a common character code, and it can be seen that the external character was previously input as character data. That is, the text DB2 (35b) of the storage means 30 stores the association of the character codes for the external characters. Therefore, if an undefined character code is assigned to an external character previously input as character data, duplication of character codes occurs. Therefore, when the association between the character code system identification information and the character code included in the current character data to be processed exists in the sentence DB2 (35b) of the storage means 30, the processing means 20 is The central processing server performs S803 processing.

 In S803, as described above, the central processing server as the processing means 20 associates the character code included in the character data to be processed with the arbitrary character management information as shown in FIG. In this case, it is stored in the sentence DB1 (35a) as the character code of company A. For example, if the current character data to be processed includes an association between the character code system identification information representing “Company B's character code” and the character code representing “250”, in S803, as processing means 20 The central processing server reads “50”, which is the character code of company A, from the text DB2 (35b) stored in the storage means 30 of FIG. “50” is associated with arbitrary character management information and stored in the sentence DB1 (35a) of the storage means 30. Thus, only the character code for the specific character code system is stored in the sentence DB1 (35a) of the storage means 30, and the other character code for the external character is stored in the sentence DB2 (35b) of the storage means 30. By storing the correspondence with the character codes in the system, the storage capacity can be saved.

[0085] By this S803, the processing for the current character data to be processed (data for one character) is completed, and the central processing server as the processing means 20 receives the previously received text data. If there is data for the next one character, check if it exists. In other words, the current character data to be processed is changed to data for the next character (association between character code system identification information and character code), and the processing is performed again from S802. For the text data received earlier, the character input process ends when the processing of the last character data is completed.

 [0086] (1-6) Subsequently, in the previous S804, the association between the character code system identification information and the character code included in the current character data to be processed is the sentence DB2 (35b) in the storage means 30. If it is determined that the unused character code does not exist in the storage means 30, the central processing server as the processing means 20 determines whether there is an unused character code in the undefined character code DB33 of the storage means 30 (S805). Specifically, the undefined character code DB 33 stored in the storage means 30 as shown in FIG. 5 stores the character codes other than the character code system identification information included in the current character data to be processed. Judgment is made based on whether or not there is a character code associated with the system identification information and indicating that the “character code use information” is not used. For example, if the current character data to be processed includes an association between the character code system identification information representing “Company B's character code system” and the character code representing “250”, For character codes related to character code system identification information other than "Code system" (Character code system of Company A, Character code system of C organization), "Character code usage information" indicates that the character code is not used. Judge whether the code exists or not. The undefined character code DB33 in Fig. 5 does not use the character code "200" for the character code system of Company A, and the character code "200" for the character code system of the C institution. This corresponds to the case where there is an unused character code in S805. Here, if there is no unused character code for either the A company's character code system or the C organization's character code system, there is no unused character code in S805. It corresponds to.

[0087] (1-7) Subsequently, if it is determined in S805 above that there is an unused character code in the undefined character code DB33 of the storage means 30, the central processing server as the processing means 20 The used character code is read together with the character code system identification information, and the undefined character code DB33 in the storage means 30 is associated with the unused character code and the used character code usage information is changed during use (S806). . And the central as processing means 20 The processing server inputs character codes into the text DBl (35a) and the text DB2 (35b) in the storage means 30 (S808). Specifically, out of the character code included in the current character data to be processed and the character code read in S806, the character code of company A and any character management information are associated with each other and stored. Is stored in the sentence DB2 (35b) of the storage means 30 in association with the character code of company A, the character code of company B, and the character code of the institution C. As a result, the character code system identification information and character code included in the current character data to be processed can be substantially arbitrarily set to the character code system identification information and character code read from the undefined character code DB33. The text DB 35 of the storage means 30 can be stored in association with the character management information.

[0088] (1 8) —On the other hand, if it is determined in S805 that there is no unused character code in the undefined character code DB33 of the storage means 30, the central processing server as the processing means 20 stores Character code conversion processing is performed using the character code conversion table DB34 of means 30 (S807). Specifically, for the specific character code system represented by the character code system identification information and the character code included in the current character data to be processed, other character code systems corresponding to the previous character code. The character code is identified and read from the character code conversion table DB34 of the storage means 30. For example, the current character data to be processed includes the association between the character code system identification information representing “B company's character code system” and the character code representing “440”, and the storage means 30 has not yet been associated. Defined character code Consider the case where there is an unused character code of Company A in DB33, but there is no unused character code of C organization. Then, the central processing server as the processing means 20 uses the character code conversion table DB34 of the storage means 30 and uses the character code of company A corresponding to the character code representing "440" for "character code system of company B". And specify the character code of C organization and read the specified character code. In the character code conversion table DB34 in Fig. 6, the character code of company A corresponding to the character code representing "440" is "520" and the character code of organization C is "600" for "character code system of company B" The character code “520” of the company A and the character code “600” of the organization C are read from the character code conversion table DB34.

[0089] After this S807, the central processing server as the processing means 20 is stored in the storage means 30. The character code is input to the sentence DBl (35a) and the sentence DB2 (35b) (S808). Specifically, among the character codes included in the current character data to be processed and the character codes read from the DB34 character code conversion table DB34 in S807, the character code of company A is associated with arbitrary character management information. Is stored in the sentence DB1 (35a) of the storage means 30, and the character code of the company A, the character code of the company B and the character code of the organization C are associated with each other and stored in the sentence DB2 (35b) of the storage means 30. As a result, the character code system identification information and character code V, which are included in the current character data to be processed, and the character code system identification information and character code read from the character code conversion table DB34, The text DB 35 of the storage means 30 can be stored in association with the arbitrary character management information.

 [0090] In S805, if there is no unused character code in the undefined character code DB33, the reason for performing the character code conversion process in S807 is that the unused character code is first converted from the undefined character code DB33. This is because, if there is a force that does not exist after searching, it is originally defined in each character code system as a second best measure, and it is similar to each other and converted into something similar. In other words, an unused character code and external character display information can display an external character as intended, but when converting to a similar external character, it is not always possible to display an external character as intended. Because there is no.

 [0091] (1-9) Force from S802 to S808 explained above For sentence data received from the input means (11 to 13), it is processing of one character data, and the last one character of the received sentence data The processing of S802 to S808 is performed until the minute data is completed. In other words, if the processing of S803 or S808 is completed and there is still unprocessed character data in the received text data, the current character data to be processed is changed to unprocessed character data and processed again from S802. I do.

 As described above, by performing the character input process of FIG. 8, sentence data corresponding to a plurality of character code systems is accumulated in the sentence DB 35 of the storage means 30. In text DB35 in Fig. 7, the text data for 3 characters (there are already 3 character management information) is accumulated, and there is a record corresponding to the 3rd character in text DB2 (35b). It can be seen that the character is an external character.

[0093] Also, in the previous S808, the external character display DB32 of the storage means 30 as shown in FIG. It is even more desirable to use the external character display information and associate it with the text DB2 (35b) in the storage means 30. That is, in S808, the external character display information corresponding to the association between the character code system identification information and the character code included in the current character data to be processed is specified and read from the external character display DB 32 of the storage means 30, In association with the character code of Company A, the character code of Company B, and the character code of Organization C, it is stored in the sentence DB2 (35b) of storage means 30. As a result, the text DB2 (35b) of the storage means 30 can store an unused undefined character code and external character display information for displaying an external character in association with each other.

 (2-1) FIG. 10 shows a case where the central processing server, which is the processing means 20 of the character code input support system, receives a text transmission command from the input means (11 to 13) of the character code input support system. It is a flowchart showing the text data transmission process to perform. As described above, text data is input from the character code input support program (client version) according to the present invention using the interface shown in FIG. 14, and the central processing unit 20 of the character code input support system is used. The processing server stores the sentence data in the sentence DB 35 of the storage means 30.

 First, the central processing server, which is the processing means 20 of the character code input support system, receives a sentence transmission command including character code system identification information from the input means (11 to 13) of the character code input support system. (S1001). Then, the central processing server as the processing means 20 stores the character code and the external character display information associated with the character code system identification information included in the received text transmission command for each character management information. Search from DB3 5 and specify (S1002). Then, the central processing server as the processing means 20 reads out the specified character code and the external character display information from the text DB 35 of the storage means 30 as sentence data, and sets the communication means managed by the central processing server as the processing means 20. Then, it transmits to the input means (11-13) which transmitted the sentence transmission command (S1003). As used herein, “communication means” refers to hardware that serves as a network interface such as a NIC as described above.

S1001 to S1003 will be described based on FIG. For example, when a text transmission command including character code system identification information representing “Company A's character code system” is received, the central processing server which is the processing means 20 is connected to the text DB1 (35a) power of the storage means 30. Character code In addition to reading, the external character display information associated with the read character code is read from the text DB2 (35b) of the storage means 30 and sent as text data for each character management information. As a result, while using the character code system of Company A, it is possible to obtain external character display information for external characters that do not exist in Company A's character code system.

[0097] On the other hand, when a text transmission command including character code system identification information representing "Company B's character code system" is received, the central processing server, which is the processing means 20, reads the text DB1 (35a) of the storage means 30. In addition to reading all character codes from, the character code of company B associated with the read character code and the external character display information are also read for each character management information. (35a) Replace the character code read out with the character code of company B read out from the text DB2 (35b), and send it as text data together with the external character display information. That is, what is stored in the text DB1 (35a) of the storage means 30 is text data based on the character code system of Company A, and is displayed on a computer adopting the character code system of Company B. Needs to be replaced with text data based on the character code system of Company B by text DB2 (35b) in storage means 30. As a result, it is possible to obtain external character display information for external characters that do not exist in Company B's character code system while using Company B's character code system. Here, when `` Replace character code read from sentence DBl (35a) with character code of company B that also read sentence DB2 (35b) force '' A corresponds to the character code read from sentence DB1 (35a) Company character code Power Text May not exist in DB2 (35b). In this case, the character code read from the sentence DBl (35a) is the common character code, and it is not necessary to replace it with the character code of company B.

(2-2) FIG. 15 shows an example of sentence data transmitted by the central processing server as the processing means 20 in the previous S 1003. In the figure, the “embedded font information” part contains the above-mentioned external character display information read out, and the “sentence” part contains the sentence DB1 (35a) and sentence DB2 (35b) force. Indicates the character code read out above! / The text data in Fig. 15 is in conformity with the SVG (Scaleable Vector Graphic) standard, and is used in the "text" part and cannot be displayed with the general character code system! The font that includes the character is converted to the SVG standard in the “embedded font information” It is defined as vector data for display on a compatible computer. The “Sentence” part represents the text data in the text data creation area in Fig. 14 according to the SVG standard. As the internal data of this "sentence" part, only the character code is stored, and external characters not defined in the character code system are defined in the "embedded font information" part. Characters are generated and displayed based on vector data. The correspondence between the character code as the internal data in the “text” part and the vector data defined in the “embedded font information” part is related by the tag “glyph unicode => j. In the “embedding font information” part of the text data that conforms to the SVG standard, the definition of vector data for external characters with a ☆ mark and the definition of vector data for external characters with a month mark are shown as examples. RU

 [0099] In SVG, fonts with only external characters are embedded, and characters that are normally defined in the character code system are displayed based on the character code as the internal data of the “sentence” part and defined in the character code system. Based on the character code as the internal data of the “text” part, the embedded font name, and the vector data defined in the “embedded font information” By displaying, the same content can be displayed on computers that use various character code systems. Fig. 16 shows an example of the text data shown in Fig. 15 displayed on a mobile phone or personal computer compatible with the SV G standard. The mobile phone of Company A and Company B in Fig. 16 does not display the full text of the text data, because this is because the mobile phone display is small. Can be viewed.

 [0100] As described above, if the character code system identification information is specified, the text data along the character code system represented by the specified character code system identification information can be acquired from the text DB 35 of the storage means 30. It can be done.

(3-1) As described above, the character code input support program (client version) according to the present invention is installed in the input means (11-13). By executing this character code input support program (client version), characters are input, and the created text data is sent to the central processing server, which is the processing means 20, so that the text data is stored in the storage means 30. Text Explained that it can be stored in DB35. On the other hand, the character deletion command By transmitting to the central processing server which is the processing means 20, the text data power and the character data can be deleted from the text DB 35 of the storage means 30. For example, a case where the bulletin board information on the Internet stored as sentence data in the sentence DB 35 of the storage means 30 is downloaded and displayed, and some characters of the bulletin board information are deleted. In addition, it also applies to the case where content is created or modified by storing text data in the text DB 35 of the storage means 30 and inputting or deleting characters from the input means (11-13). . This character deletion process will be described with reference to FIG.

 [0102] (3-2) First, using the input means (11-13) of the character code input support system, the interface of the character code input support program (client version) as shown in Fig. 14 From the "Data creation area", select the character you want to delete and issue a delete command. The input means (11 to 13) of the character code input support system identifies the character for which the deletion command has been issued, manages that character, and transmits a character deletion command including character management information! Central processing server power as the processing means 20 of the character code input support system The character deletion command is received via a communication network or the Internet (S901). Character management information is included in the character deletion command sent by this input means (11-13) because it specifies which of the characters stored in sentence DB35 of storage means 30 is to be deleted. It is to do.

(3-3) Then, the central processing server as the processing means 20 performs the character deletion process for each character management information for one character in response to the received character deletion command. First, the central processing server as the processing unit 20 stores the character code system identification information and the character code associated with the current character management information to be processed in the received character deletion command. Text DB35 is searched and specified. Specifically, the central processing server as the processing unit 20 specifies the character code associated with the character management information included in the character deletion command from the sentence DB1 (35a) in the storage unit 30 (S902). ). Then, the central processing server as the processing means 20 determines whether other character management information associated with the character code identified from the sentence DB1 (35a) exists in the sentence DB1 (35a) of the storage means 30. (S903). For example, it is assumed that the current character management information to be processed in the received character deletion command is “2” in the state of sentence DB1 (35a) and sentence DB2 (35b) in FIG. In this case, from the sentence DB1 (35a) of the storage means 30, “2” corresponding to the character management information “ 3 ”can be identified, and it is determined whether the identified“ 3 ”company A character code exists in association with other character management information in the text DBl (35a) of the storage means 30. To do.

 (3-4) Subsequently, in S903, if it is determined that other character management information associated with the character code specified in S902 exists in the sentence DBl (35a) of the storage means 30, the processing means 20 The central processing server deletes the association between the character code identified in S 902 and the current character management information to be processed from the sentence DBl (35a) of the storage means 30 (S904). Specifically, the central processing server as the processing means 20 may delete the record of the character management information currently being processed from the received character deletion command from the sentence DB1 (35a) of the storage means 30. Applicable. For example, in the state of sentence DBl (35a) and sentence DB2 (35b) in FIG. 7, it is assumed that the current character management information to be processed in the received character deletion command is “2”. In this case, the record corresponding to the character management information “2” is deleted from the sentence DBl (35a) in the storage means 30. Thus, in S903, if it is determined that the character management information associated with the character code specified in S902 exists in the text DBl (35a) of the storage means 30, the character code is released from the undefined character code DB. Necessary power for processing etc. S! Therefore, do not process S905 or S906! / 906.

 [0105] Then, in S904, the processing for the current character management information to be processed in the received character deletion command is completed, and the central processing server as the processing means 20 determines the previously received character deletion command. Then, it is confirmed whether the character management information for the next one character exists, and if it exists, the processing of S902 is performed. That is, the current character management information to be processed is changed to the character management information for the next one character, and the processing is again performed from S902. When the character management information for the last character has been processed for the previously received character deletion command, the character deletion processing ends.

[0106] (3-5) If it is determined in the previous S903 that the character management information associated with the character code specified in S902 does not exist in the sentence DBl (35a) of the storage means 30, the processing means 20 The central processing server identifies the record containing the character code identified in S902 from the text DB2 (35b) in the storage means 30, and identifies the character code system identification information and character code contained in the identified record. Character code associated with the association with The use presence / absence information is identified from the undefined character code DB33 of the storage means 30, and the use presence / absence information is changed to information indicating “unused” and stored in the undefined character code DB33 of the storage means 30 (S905). .

 This process will be described using the undefined character code DB33 in FIG. 5 and the sentence DB35 in FIG. 7 as examples. Records containing the character code “50” specified in S902 (records of character code “50” from company A, character code “250” from company B, character code “50” from company C) Character code system identified from DB2 (35b) and the association between the character code system identification information and character code included in the identified record (Company A = character code “50”, company = character code “25 0”, C institution = Character code use / non-use information related to character code “50”) is memorized from undefined character code DB33 of storage means 30, and the use / presence information is changed to information indicating “unused” and stored. The undefined character code DB33 of means 30 is stored. In the undefined character code DB33 in Figure 5, the character code usage information corresponding to Btt = character code “250” is “in use”, and the character code usage information corresponding to C institution = character code “50” is used. Is “in use”. Therefore, change these two character code usage information to “unused” to release the undefined character code so that it can be assigned again when a character is entered. Here, the undefined character code DB33 in Fig. 5 does not have character code use / non-use information corresponding to eight companies = character code “50”. The record power of the character code “50” of company A, the character code “250” of company B, and the character code “50” of company C The character code originally existing in the character code system of company A is “50”. Represents the power!

(3-6) Subsequent to S905, the central processing server as the processing means 20 associates the character code specified in S902 with the current character management information to be processed in the text DB1 ( In addition to deleting from 35a), the record containing the character code specified in S902 is deleted from the sentence DB2 (35b) in the storage means 30 (S906). For example, in the state of sentence DB1 (35a) and sentence DB2 (35b) in Fig. 7, the association between the character code specified in S902 and the character management information ^ character management information = 3, character code = 50 '' is stored. Delete the character management information record “3” from the sentence D Bl (35a) of means 30, and store the first line record that contains the character code “50” of company A specified in S902. Meaning 30 sentence D Delete from B2 (35b).

 [0109] (3-7) From S902 to S906 described above, the sentence deletion command received from the input means (11 to 13) is a character deletion process for one character, and the last sentence of the received sentence deletion command The processes of S902 to S906 are performed until the character deletion process for one character is completed. In other words, if the processing of S904 or S906 ends and there is still unprocessed character management information in the received text deletion command, the current character management information to be processed is changed to unprocessed character management information. Process from S902 again.

 [0110] In this way, by performing the character deletion process of Fig. 9, the sentence data characters stored in the sentence DB3 5 of the storage means 30 are deleted, and at the same time, undefined characters that are no longer used. For the code, the undefined character code DB33 character code use / non-use information in the storage means 30 becomes unused, and the undefined character code is released. As a result, the character deletion process can be performed while effectively using the character code of the undefined character code DB33 of the storage means 30.

 [0111] 3. Other embodiments of the present invention

[0112] (1) Character code conversion table DB34 of storage means 30 is a data structure for storing a character code conversion table in which a plurality of associations between character code system identification information and character codes are associated, as shown in FIG. Explained. However, the character code conversion table DB34 stored in the storage means 30 is stored in association with a “priority level” in a character code conversion table in which multiple associations between character code system identification information and character codes are associated as shown in FIG. The data structure to be used may be used. That is, priorities are assigned to the character code conversion table, and conversion processing is performed according to the priorities in the previous character input conversion processing (S807). For example, in the state of character code conversion table DB34 in Fig. 11, there is no unused character code in Company B's undefined character code for Company A's character code "410", and S807 character code conversion processing is required Suppose there is. Then, first, the character code conversion table with priority level “2” is applied, and the character code of company B is “490”. Also, by setting a priority level (application order) in this character code conversion table DB34, it is possible to preferentially convert external characters that are closer in concept within the character code conversion table. Memory If there is no unused undefined character code in the undefined character code DB33 at stage 30, it is closer to the concept by using the priority level (order of application) of the character code conversion table. External character power can also be converted.

 [0113] (2) Also, the common character code DB31 of the storage means 30 as shown in Fig. 3 is used to determine the common character code of S802. Instead of the common character code DB31, Fig. 12 The common character range DB37 as described above may be stored in the storage means 30, and the common character code of S802 may be determined. That is, the common character range DB37 in FIG. 12 stores the character code usage status, the character code start and the character code end in association with each other, and specifies the usage status of the specific character code range. Can do. For example, the common character range of DB37 in Fig. 12 indicates that the character code in the range of “1000 to 1200” is the common character code, the character code in the range of “1201 to 1600” is the reserved character code, and the range of “1601 to 2000” It can be seen that the character code of is an undefined character code, and the character code in the range of “2001 to 3000” is a common character code. Therefore, the common character code of S802 can be determined depending on whether or not the input character code is within the character code range of the common character code.

 [0114] (3) Furthermore, the sentence DB 35 of the storage means 30 has a data structure as shown in FIG. 7, and it is described that the sentence DB 35 includes the sentence DB 1 (35a) and the sentence DB 2 (35b). A data structure such as That is, the text DB 35 in FIG. 13 stores character management information, character code system identification information, and character codes in association with each other, and character code system identification corresponding to each character (each character management information). Information and character codes can be specified. By adopting the data structure of sentence DB35 in Fig. 13, if the character code system identification information is specified in the text data transmission process shown in Fig. 10, the association between the character management information and the character code can be more specified. A few steps can be performed by computer processing.
