Description

  The present invention relates to a computer system 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.

  Characters that are not defined in a standardized character code system such as the JIS standard are generally not supported by word processing software and the like, and therefore cannot be input / output by computer processing. 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 do not exist in the standardized character code system are subject to input / output computer processing. It can be.

  For example, even in JISX0208, which is a standard generally used as a Japanese character code, characters called “model-dependent characters” or “vendor-specific characters” by communication carriers and hardware manufacturers in undefined areas of character codes Is often defined. Since these “model-dependent characters” or “vendor-specific characters” cannot be input or output on a computer of another company other than the company that defined the characters, there is a problem in terms of compatibility.

  In addition, even in a mobile phone which is a small computer, a special character for displaying a specific picture in an area of one character called an “pictogram” using an undefined area of the character code system of each communication carrier Is defined. Examples of pictures displayed by these “pictograms” include various things such as human faces, animals, food, plants, shops, and national flags. However, this “pictogram” is assigned by each communication carrier (mobile phone company) to an undefined area of a standard character code system such as JISX0208, and there is no compatibility between the communication carriers. Therefore, even if an e-mail including the character code of “pictogram” input on the mobile phone of communication carrier A is transmitted to the mobile phone of communication carrier B, the “pictogram” is correctly displayed on the mobile phone of communication carrier B. It is impossible to do so, and the so-called “garbage” phenomenon occurs. Therefore, the “pictogram” uniquely defined by each communication carrier has the inconvenience that it can only 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 that defines a unique “pictogram” in an undefined area of the character code in the character code system. -ing

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

  1. As a prior art for solving this inconvenience, there is a method of performing mutual conversion of character codes of “pictograms” uniquely defined between communication carriers. For example, a correspondence table of character codes of pictographs in each communication carrier is created such that a pictograph of “smile” in communication carrier A is converted into a pictograph of “smile” in communication carrier B. As a result, even if an e-mail including a pictograph is transmitted to a mobile phone of a communication carrier (destination) different from the communication carrier (sender) of the mobile phone used for creating / transmitting the e-mail, Although the design of the details of is different, it can be converted into pictograms that are common in concept. That is, according to the correspondence table of pictogram character codes in each communication carrier, at the time of e-mail transmission, the pictogram character code of the e-mail transmission source communication carrier is converted to the pictogram character code of the destination communication carrier. .

  However, the method of creating the correspondence table of pictogram character codes in each communication carrier is only to convert them to similar pictograms, and to distribute content of the same design to mobile phones belonging to any communication carrier It cannot meet the needs of content providers. In addition, when mutually converting to similar pictograms, the impression of the entire content by the converted pictograms may change to content with an impression quite different from the design originally created and intended by the content provider There is. Furthermore, in the case of mutual conversion to similar pictograms, there is a disadvantage that conversion itself cannot be performed if pictograms corresponding to pictograms of the transmission source communication carrier are not present at all in the pictograms of the transmission destination communication carrier.

  2. As another conventional technique, in a personal computer connected to the Internet, to send to a mobile phone, an e-mail including a pictograph that is a unique definition of a mobile phone communication carrier is input and created. Support software exists for this purpose.

  However, in such pictogram input support software, the same character code may be adopted as the pictogram character code in the character code system of each communication carrier. Therefore, to prevent garbled characters, the character code system of a specific company You can only enter pictographs. Accordingly, only the pictographs of one communication carrier can be input and used, and the user must first select which communication carrier's pictographs are to be input. Also, the input pictogram data is naturally not defined in the character code system adopted by the personal computer, and the tag data (for example, <IMG SRC = 0351.gif> Or any combination of a plurality of characters (for example, | 003 |). For this reason, when html tag data or a combination of a plurality of characters is input, even if the user does not intend to input a pictogram, the support software recognizes that the input of a specific pictogram is instructed. Therefore, unexpected garbled characters appear in pictograms due to html tag data and combinations of multiple characters.

  For example, under the support software that adopts the rule that “HTML tag data <IMG SRC = 0351.gif> represents a specific pictogram”, the original “0351.gif file on the WEB server is displayed. You will not be able to give the command Similarly, under the support software that adopts the rule that “a character string“ | 003 | represents a specific pictogram ””, an original instruction “display a character string“ | 003 | ”can be given. Disappear.

  1,

  (1) Therefore, in order to solve the above problems, 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. Character code input for users to input without being aware of the existence of characters (external characters) that are defined only in some of the character code systems among the multiple character code systems. It is a support system.

  The storage means of the character code input support system includes: character code system identification information for identifying the character code system; character codes in the character code system represented by the character code system identification information; and characters of a single character code system. A single character code conversion DB for storing the codes in association with each other, a character management information for managing the input characters, and a sentence DB for storing the character codes of the single character code system in association with each other. Yes.

  Then, the processing means of the character code input support system (1) accepts input of the character code system identification information and character code as a character input command via the input means, (2) the input The character code of the single character code system associated with the identified character code system identification information and the character code is searched and specified from the single character code conversion DB of the storage means, and the character of the specified single character code system is identified. The code is read from the single character code conversion DB of the storage means, and is stored in the sentence DB of the storage means in association with the arbitrary character management information.

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

  Examples of the “character code system” include various character code systems such as a JIS code standard, an ASCII code standard, a Unicode code standard, an ISO code standard, a character code standard unique to a communication carrier or a hardware manufacturer, and the like. “Character code” means individual character codes constituting the character code system. The “character” in the “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 one byte as one character, 256 character codes can be used, so that a maximum of 256 characters can be defined. Similarly, if the character code system has two characters as one character, 65536 character codes can be used, so that a maximum of 65536 characters can be defined.

  "External character" is a character that is defined in only some of the character code systems among the multiple character code systems. When displayed in an undefined character code system, problems such as garbled characters occur. A character that would end up. Examples of external characters include characters representing a specific picture called “pictograms” uniquely defined by mobile phone communication carriers, and model-dependent characters depending on a specific hardware environment. In addition, when there is a character code system representing Japanese characters and a character code system representing Chinese, characters other than Kanji characters and symbols common to both countries are external characters.

  The “single character code system” is a character code system for integrating multiple character code systems, and has character code definitions corresponding to the character codes of two or more character code systems to be managed. It is a character code system. For example, if one character is defined by 4 bytes as the “single character code system”, a plurality of character code systems representing one character by 2 bytes can be managed. “Character code system identification information” is management information for identifying each character code system, and corresponds to information including one or more numerical values and symbols, for example. “Character management information” is management information of character data in text data, and is management information in units of one character or a plurality of characters. This “character management information” manages the order of character arrangement in order to display a set of characters meaningfully as sentence data. The “arbitrary character management information” is the convenient management information of the character data in the text data because the “character management information” itself is, for example, when a new character input command is received, This means that any method of system designers such as numbering may be used. In other words, the numbering method of the character management information may be any method as long as it can manage the order of the character data in the text data.

  The “single character code conversion DB” is a single character corresponding to a specific character code in a specific character code system by storing character code system identification information, a character code, and a character code of the single character code system in association with each other. The character code of the code system can be specified. Further, by storing the character management information and the character code of the single character code system in association with each other in the “text DB”, it is possible to specify the text data as a set of character codes of the single character code system. The meaning of “association of information” in the present invention does not necessarily mean that information to be associated is stored in one logical record, and there are two DBs such as “single character code conversion DB” and “text DB”. You may be comprised from the above multiple DB. That is, “association of information” in “single character code conversion DB” and “text DB” means that it is only necessary to specify the information to be obtained by “association of information”.

  The “character input instruction” is information for instructing input of a character, and includes information (character code system identification information and character code) indicating which character code system is to be input. Further, the “character input command” is not necessarily an input command for 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” Is included.

  The above definitions also apply to the following inventions.

  (3) When the present invention is used, the character management information is converted by converting the character code in the specific character code system represented by the character code system identification information and the character code input from the input means into the character code of the single character code system. Can be stored in the sentence DB of the storage means.

  As a result, even if the user is not particularly conscious, there is no need to worry about garbled characters due to external characters (no duplication of character codes) on computers in different character code system environments, and single character code systems It is possible to create a sentence with the character code. That is, users in multiple character code systems (for example, character code systems of different communication carriers and character code systems based on different languages such as Japanese, Chinese, Korean, English) It is possible to create a sentence with a character code of a single character code system while maintaining the character code system adopted by the computer.

  2,

  (1) In addition, a character code input support system according to another invention includes, in the storage unit, character code system identification information for identifying the character code system, and a character code in the character code system represented by the character code system identification information. A single character code conversion DB that stores external character display information that is information for displaying an external character that is not defined in the character code system, and a character code of a single character code system, and an input character A character DB that stores character management information to be managed and character codes of the single character code system in association with each other is stored.

  Then, the processing means of the character code input support system (1) accepts an input of a text transmission command via the input means, (2) a single character code system from the text DB stored in the storage means The character code system identification information and the character code system identification information represent the character code of the read single character code system based on the single character code conversion DB stored in the storage means. Converting the character code and external character display information in the code system into an association and reading them from the storage means; (3) associating the character code system identification information, the character code and the external character display information read out by the conversion; It transmits to the said external system via the said communication means as text data, It is characterized by the above-mentioned.

  (2) Here, “external character display information” is information for displaying an external character that is not defined in each character code system. For example, font information such as vector fonts including dot fonts and outline fonts, This corresponds to picture (bitmap) data. Further, in the “single character code conversion DB”, by storing the character code system identification information, the character code, the external character display information, and the character code of the single character code system in association with each other, the character code of the single character code system can be obtained. In a character code system in which a character to be represented is not defined, external character display information for displaying the character can be specified. As a result, even in a computer in an environment of a character code system that does not adopt a specific character represented by the character code of the single character code system, the “character code system identification information, character code, and external character display information” Specific characters can be displayed.

  “External system” means that the computer is different from the processing means of the character code input support system. For example, the input means for receiving a command from the user may be an external system at the same time. . That is, a computer (such as a mobile phone or a personal computer) as an input means and an external system transmits a text transmission command to the processing means of the character code input support system and receives text data from the processing means of the character code input support system This is also the case. The “communication means for communicating with an external system” corresponds to hardware that serves as an interface with a communication network such as a NIC. The “text transmission command” is information for instructing transmission of text data. In addition, when “reading the character code of the single character code system from the text DB stored in the storage means”, in order to maintain the order of the characters as the text data, it is related to the character code of the single character code system. It reads based on the order of the character which the said character management information represents.

  The above definitions also apply to the following inventions.

  (3) By using the present invention, the association between the character code system identification information, the character code, and the external character display information corresponding to the character code of the single character code system of the text DB stored in the storage means is specified, and the text Data can be sent to an external system.

  As a result, in a computer (external system) in an environment using a specific character code system, the characters defined in the character code system can be displayed by the character code system identification information and the character code. Characters not defined in the system can be displayed by the character code system identification information, the character code, and the external character display information. In particular, in the “single character code conversion DB”, the character code system identification information, the character code, the external character display information, and the character code of the single character code system are associated in advance for all the character codes of the character code system to be managed. If prepared, text data having the same contents can be displayed on a computer in an environment using any character code system.

  3,

  (1) In addition, a character code input support system according to another invention includes, in the storage unit, character code system identification information for identifying the character code system, and a character code in the character code system represented by the character code system identification information. A single character code conversion DB that stores external character display information that is information for displaying an external character that is not defined in the character code system, and a character code of a single character code system, and an input character A character DB that stores character management information to be managed and character codes of the single character code system in association with each other is stored.

  Then, the processing means of the character code input support system (1) accepts input of the character code system identification information as a text transmission command via the input means, (2) is stored in the storage means The character code of the single character code system is read from the sentence DB, and the character code system of the input is read out based on the single character code conversion DB stored in the storage means. Converting the association between the character code and the external character display information in the character code system represented by the identification information and reading it from the storage means; and (3) associating the association between the character code and the external character display information read out after the conversion. The data is transmitted to the external system via the communication means.

  (3) By using the present invention, the association between the character code system identification information, the character code, and the external character display information corresponding to the character code of the single character code system of the sentence DB stored in the storage unit is specified, and the external Can be sent to the system. In particular, the character code and the external character display information in the character code system represented by the character code system identification information input from the input means can be transmitted as text data.

  As a result, in a computer (external system) in an environment using a specific character code system, the characters defined in the character code system can be displayed by the character code system identification information and the character code. Characters not defined in the system can be displayed by the character code system identification information, the character code, and the external character display information. In “Single Character Code Conversion DB”, the character code system identification information, the character code, the external character display information, and the character code of the single character code system are prepared in advance for all the character codes of the character code system to be managed. If so, text data having the same content can be displayed on a computer in an environment using any character code system. In particular, since the character code input support system can identify and transmit the character code and the external character display information in the character code system represented by the character code system identification information input from the input means, the text data display processing in the external system Can be made faster.

  4,

  (1) In addition, a character code input support system according to another invention includes, in the storage unit, character code system identification information for identifying the character code system, and a character code in the character code system represented by the character code system identification information. A single character code conversion DB that stores external character display information that is information for displaying an external character that is not defined in the character code system, and a character code of a single character code system, and an input character A text DB that stores character management information to be managed, a character code of the single character code system in association with each other, and the character code system identification information for specifying an undefined character code in a specific character code system; An undefined character code DB that stores character codes in association with each other is stored.

  Then, the processing means of the character code input support system (1) accepts input of the character code system identification information as a text transmission command via the input means, (2) is stored in the storage means The character code of the single character code system is read from the sentence DB, and the character code system of the input is read out based on the single character code conversion DB stored in the storage means. Converting the character code in the character code system represented by the identification information into an association between the character code and the external character display information, and reading from the storage means; (3) the character code system represented by the input character code system identification information in the conversion If there is no character code, the undefined character code DB stored in the storage means is used. Converting the input character code system identification information into an undefined character code, and (4) associating the converted character code with external character display information as sentence data via the communication means. It is characterized by transmitting to.

  (2) Here, the “undefined character code DB” is a DB for specifying an undefined character code (an undefined character code to which a specific character is not assigned) in a specific character code system. The character code system identification information and the character code are associated with each other.

  The above definitions also apply to the following inventions.

  (3) By using the present invention, the association between the character code system identification information, the character code, and the external character display information corresponding to the character code of the single character code system of the sentence DB stored in the storage unit is specified, and the external Can be sent to the system. In order to display an external character that does not exist in the character code system, a combination of an undefined character code and external character display information in the character code system is required. In the present invention, even if a character code in the character code system represented by the character code system identification information input from the input means does not exist in the single character code conversion DB, an undefined character code system in the character code system is based on the undefined character code DB. It can be converted to a defined character code and sent.

  As a result, in a computer (external system) in an environment using a specific character code system, the characters defined in the character code system can be displayed by the character code, and are not defined in the character code system. Characters can be displayed by a character code and external character display information. In particular, since the character code is converted based on the undefined character code DB, it is not necessary to set the association between the undefined character code and the external character display information in advance in the single character code conversion DB. Effective use of character codes as resources is possible.

  (1) Moreover, the character code input program which concerns on another invention makes the said processing means perform the said process in the said character code input assistance system, It is characterized by the above-mentioned.

  As described above, when the present invention is used, the character code in the specific character code system represented by the character code system identification information and the character code input from the input means is converted into the character code of the single character code system and the character is converted. It can be associated with management information and stored in the text DB of the storage means.

  This makes it possible to create a sentence using a single character code system character code without worrying about garbled characters due to external characters on a computer in an environment with a different character code system, without the user being particularly conscious. . That is, users in a plurality of character code systems (for example, character code systems such as JIS code standard, ASCII code standard, Unicode standard, Japanese, Chinese, Korean, English, etc.) are adopted by each computer. It is possible to create sentences using the character code of the single character code system.

  Further, by using the present invention, it is possible to identify the association between the character code and the external character display information corresponding to the character code of the single character code system of the sentence DB stored in the storage means, and transmit it to the external system as sentence data. .

Characters can be displayed by associating character codes with external character display information. In particular, in the “single character code conversion DB”, the character code system identification information, the character code, the external character display information, and the character code of the single character code system are associated in advance for all the character codes of the character code system to be managed. If prepared, text data having the same contents can be displayed on a computer in an environment using any character code system.

  Embodiments of the present invention will be described below with reference to the drawings.

  1. About 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 and a personal computer, a processing means 20 as a central processing server, and the central processing server. And storage means 30 which is a storage device such as an HDD to be managed. And input means (11-13), such as a portable information terminal and a personal computer, and the processing means 20 as a central processing server are connected via communication lines, such as a communication network and 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, in the case of being composed of a plurality of computers as shown in FIG. 1, character code input work and text data can be input from various information terminals with different character code systems such as portable information terminals and personal computers. Browsing is possible.

  The components in FIG. 1 will be described in further detail. The input means 11 is a mobile phone as a mobile information terminal, and is 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 mobile information terminal, and is a mobile phone that employs 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 personal computers by a C organization which is a character code standardization organization.

  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 which is a communication company, a communication server of company A, and a wide-area communication network (Via the Internet etc.) That is, when the input means 11 which is a mobile phone of company A communicates with a communication network other than company A, it is performed via a 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. Further, 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.

  The input means 11, which is a mobile phone of company A, can usually input only the characters 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, characters that are not adopted in the company A character code system (for example, other companies) And the 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 also 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 unit 30 which is a storage device such as an HDD and managed by the central processing server as the processing unit 20 in FIG. 1 will be described. The storage means 30 stores a single character code conversion DB 31, a sentence DB 32, an undefined character code DB 33, a character code input support program 34, and an OS / other program 35 in the form of a file or database. .

  And the central processing server as the processing means 20 reads each information (31-35) memorize | stored in the memory | storage means 30, and interprets and performs a program and data. Further, the central processing server as the processing means 20 interprets and executes the OS / other program 35 and the character code input support program 34 stored in the storage means 30, thereby executing the character code input process according to the present invention. Etc. are performed.

  (3) Then, each information (31-35) memorize | stored in the memory | storage means 30 which is a memory | storage device is demonstrated using FIGS.

  The “single character code conversion DB 31” illustrated in FIG. 3 includes a character code of a single character code system, character code system identification information, a character code in the character code system represented by the character code system identification information, and external character display information. Store in association. By associating the character code system identification information, the character code, and the external character display information, “what character code represents in the specific character code system” and “specific character “External character display information for expressing an external character code defined in the code system in another character code system” can be specified. In FIG. 1, it has been described that there are three types of character code systems (A company, B company, C organization) as an example, but FIG. 3 also stores data by taking these three types of character code systems as examples. . If the “character code of the single character code system” is the same, the same character is represented. For example, a character whose “character code” of “Company A's character code system” is “50” and a character whose “character code” of “Character code system of B company” is “100” Since the “character code” is the same as “1”, it represents the same character.

  From the “single character code conversion DB 31” illustrated in FIG. 3, in order to represent a specific character whose “character code of the single character code system” is “1”, “Code” must be “50”, “Character code” of “Company B” should be “100”, and “Character code system of C organization” should be “50”. I understand that. In addition, in order to represent a specific character whose “character code of the single character code system” is “2”, in the “character code system of Company A”, the “character code” may be “200”. In “Character code system of B company” and “Character code system of C organization”, it can be seen that the corresponding “character code” does not exist and is a character code unique to A company. In this case, in order to represent a specific character whose “character code of the single character code system” is “2” as a character in “character code system of company B” or “character code system of organization C”, “Vector data A1” that is “external character display information” associated with “character code” of “200” in “character code system of” may be used. Similarly, in order to represent a specific character whose “character code of single character code system” is “3”, “character code” of “Character code system of company B” is “300”, “ In the “character code system”, it is understood that the “character code” may be “400”. Furthermore, in order to represent a specific character whose “character code of the single character code system” is “3” as a character in the “character code system of company A”, “vector data B1” or “external character display information” or “ It can be seen that the “vector data C1” may be used.

  In the “text DB 32” illustrated in FIG. 4, character management information for managing characters input from the input means of the character code input support system and character codes of a single character code system are stored in association with each other, whereby a single character code is stored. Sentence data as a set of system character codes can be specified. Since the set of “character codes of a single character code system” associated with each order of “character management information” (1, 2, 3, 4,...) Is text data, in the example of FIG. 1, 1, 3, ... ".

  The “undefined character code DB 33” illustrated in FIG. 5 is a DB that stores character code system identification information, character codes, and character code use presence / absence information that indicates whether or not a character code with undefined characters is used. It is. For example, if a character code system is specified from the above three types of character code systems (A company, B company, C organization), a character code in which no character is defined in the character code system, and a character for the character code It is possible to specify the code usage information. In the “undefined character code DB 33” illustrated in FIG. 5, the “character code system identification information” representing “the character code system of company A” includes “character code use” of “500” and “character code use” of “use”. Association with “existence information”, association with “character code” “510” and “character code usage information” “unused”, and the like are associated. As a result, the “character code” “500” in which the character existing in the character code system of company A is undefined is assigned an external character existing in another character code system and is “used”. , “510” can be identified as an “unused” state in which an external character existing in another character code system is not assigned. In order to display a character that is not defined in a specific character code system on a computer that employs the character code system, a combination of an undefined character code and external character display information in the character code system is required. Therefore, the existence of the “undefined character code DB 33” is significant in order to effectively assign an undefined character code in the character code system which is a limited resource.

  The character code input support program 34 is a computer program for performing computer processing according to the present invention. The OS / other program 35 is a computer program for assisting the execution of the character code input support program 34. For example, the OS or middleware, input / output or communication for basic software as a computer program. Applicable to various application software.

  2. About the flow of the present invention

  Next, an operation flow of processing performed by interpreting and executing the character code input support program 34 according to the present invention by the central processing server as the processing means 20 of the character code input support system will be described. Hereinafter, two processes of the character input process and the character data transmission process will be described with reference to FIGS.

  (1-1) FIG. 6 shows a character input process 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 (11-13) of the character code input support system. FIG. First, the user of an input means inputs a character into the input means (11-13) of a character code input support system, and produces sentence data. Specifically, the user of the input means (11, 12), which is a mobile phone as a mobile information terminal, creates text data using an input button of the mobile phone, or is a personal computer as an information terminal. This corresponds to the case where the user of the input means (13) creates sentence data using a mouse or keyboard of a personal computer.

  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 employs, for example, the one shown in FIG. 8 as an interface for character input displayed on a screen such as a display. As shown in the figure, the character input interface of the editor program is composed of a “text data creation area” and an “external character selection area”. Characters that are commonly defined in any of the character code systems of Company A, Company B, and Organization C are entered directly into the “text data creation area” and some of the Company A, Company B, and Organization C The external characters that are defined only in the character code system are selected and input from the “external character selection area”. In the figure, an external character in any of the character code systems of Company A, Company B, and C organization can be selected and input from the “external character selection area”. The contents of the text data that can be created now are displayed in the “text data creation area”.

  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 can be selected and input from an “external character selection area”. Since external characters in a plurality of character code systems do not consider the consistency of character code assignment between them, different external characters may be defined for the same character code. For example, the character represented by the character code “1100” is different 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 input means (11 to 13) of the character code input support system provides information on the external character of one character. The character code system identification information and the character code are associated and stored internally (stored in a storage device). 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 is associated with the character code defined for the external character of company B Remember it internally. Input means in which input is performed when characters defined in common in a plurality of character code systems are directly input to the "text data creation area" in the interface of the character code input support program (client version) The character code system identification information about the character code system employed by (11-13) and the character code are stored in association with each other. 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 an external character in a plurality of character code systems can be selected and input.

  (1-2) Subsequently, when the creation of the text data is finished by the input means (11-13) of the character code input support system, the user inputs the created text data from the input means (11-13). The input unit (11-13) is instructed to transmit to the central processing server as the processing unit 20 of the support system. Then, the input means (11-13) of the character code input support system transmits the input text data, and the central processing server as the processing means 20 of the character code input support system via the communication network or the Internet. Then, text data as a character input command is received (S101). As described above, the text data transmitted by the input means (11 to 13) includes data for one character, which is formed by associating character code system identification information with a character code. Thereby, it is possible to specify which character code in which character code system represents the data for one character data, and by having a plurality of associations between the character code system identification information and the character code, a plurality of characters It becomes sentence data consisting of. Furthermore, the order of each character in the text data composed of a plurality of characters is, for example, a method in which the central processing server as the processing means 20 of the character code input support system receives the text data as an electrical signal. .

  (1-3) Then, the central processing server as the processing means 20 performs character input processing for each character data for the received sentence data. First, the central processing server as the processing means 20 converts the received text data into a character code of a single character code system based on the single character code conversion DB 31 stored in the HDD as the storage means 30 (S102). . Specifically, as shown in FIG. 3, a single character code conversion DB 31 stored in the HDD as the storage means 30 managed by the central processing server as the processing means 20 is used to store one character in the received sentence data. The “association of character code system identification information and character code” is converted to “character code of single character code system”. For example, based on the single character code conversion DB 31 of FIG. 3, “Character code” of “Company A's character code system” is “200”, “Character code” of “Company A's character code system” is “50”, “ The text data of 4 characters, “character code” of “Character code system of company B” is “100”, and “character code” of “character code system of C organization” is “400” is “2”, “1”. , “1” and “3” can be converted to “character codes of a single character code system”.

  (1-4) Next, the central processing server as the processing unit 20 stores the converted character code of the single character code system in the sentence DB 32 of the HDD as the storage unit 30 in association with arbitrary character management information. (S103). For example, assuming that the order of the “character code of the single character code system” converted in S102 is “2”, “1”, “1”, “3”, the sentence DB 32 as shown in FIG. Is stored in the HDD.

  In this way, the central processing server as the processing means 20 accepts text data (including one or more character code system identification information and character code associations) as a character input command via the input means. Then, the central processing server as the processing means 20 obtains the character code system identification information and the character code for each character (association between one character code system identification information and the character code) from the input sentence data. The character code of the single character code system associated with is retrieved from the single character code conversion DB 31 of the HDD as the storage means 30 and specified. Then, the central processing server as the processing unit 20 reads out the character code of the specified single character code system from the single character code conversion DB 31 of the HDD as the storage unit 30 and stores it in association with the arbitrary character management information. The information is stored in the sentence DB 32 of the HDD as the means 30.

  As described above, by performing the character input process of FIG. 6, sentence data corresponding to a plurality of character code systems is accumulated in the sentence DB 32 of the storage unit 30. In the above description, an example in which text data is newly stored in the text DB 32 of the HDD serving as the storage unit 30 has been described. However, the same processing is performed for overwriting and updating text data in the text DB 32 of the HDD serving as the storage unit 30. Can be realized by processing.

  Further, in the single character code conversion DB 31 of the HDD as the storage means 30 as shown in FIG. 3, all the character codes of the character code system to be managed (in the example, Company A, Company B, and Organization C) are all stored in advance. It is desirable to memorize it. By doing so, any character code of the character code system to be managed can be converted into a character code of a single character code system without omission.

  (2-1) FIG. 7 shows text data performed by the central processing server, which is the processing means 20 of the character code input support system, when a text transmission command is issued from the input means (11-13) of the character code input support system. It is a flowchart showing a transmission process.

  First, the central processing server which is the processing means 20 of the character code input support system receives a text transmission command including character code system identification information from the input means (11-13) of the character code input support system (S201). In this description, it is assumed that the character code system identification information included in the sentence transmission command is information representing “a character code system of company A”.

  (2-2) Next, the central processing server which is the processing means 20 searches and specifies and reads out the character code of the single character code system from the sentence DB 32 of the HDD as the storage means 30 for each character management information. (S202). For example, in the state of the sentence DB 32 in FIG. 4, the central processing server as the processing means 20 “character code of single character code system” in the order of “2”, “1”, “1”, “3”. Can be read out.

  (2-3) Then, the central processing server which is the processing means 20 determines whether or not the text data conversion process has been completed (S203). If it is determined that the text data conversion process has been completed, a transmission process to an external system is performed. (S206). Whether or not the text data conversion process has ended is determined by whether the character code conversion processes in S204 and 205 have been completed for all “character codes of the single character code system” read from the text DB 32 of the HDD as the storage means 30 in S202. Judgment is based on whether or not.

  (2-4) If it is determined in S203 that the text data conversion process has not ended, the central processing server as the processing means 20 uses the single character code system character code read out in S202 as the storage means 30. Based on the single character code conversion DB 31 of the HDD, the character code system identification information, the character code, and the external character display information are converted into associations and read from the HDD as the storage means 30 (S204). For example, in the state of the sentence DB 32 in FIG. 4, “character code of single character code system” in the order of “2”, “1”, “1”, “3” could be read in S202. Therefore, in this S204, the central processing server which is the processing means 20 for the “character codes of the single character code system” in the order of “2”, “1”, “1”, “3” is used as the storage means 30. Based on the HDD single character code conversion DB 31, the character code system identification information, the character code, and the external character display information are associated with each other.

  More specifically, S204 will be described. The “character code of the single character code system” of “1” is converted into “character code system of company A” by the single character code conversion DB 31 of FIG. And “Character code” is “50”, “Character code system identification information” is “Company B's character code system”, and “Character code” is “100”. The information can be converted into an association of information in which “code system identification information” is “character code system of C organization” and “character code” is “50”. Similarly, “character code of single character code system” of “2” is “character code system” because “character code system identification information” is “character code system of company A” by the single character code conversion DB 31 of FIG. Is “200” and “external character display information” is “vector data A1”. In addition, the “character code of the single character code system” of “3” is determined by the single character code conversion DB 31 of FIG. 3 so that “character code system identification information” is “Character code system of company B” and “character code” is Association of information that is “300” and “external character display information” is “vector data B1”, “character code system identification information” is “character code system of C organization”, and “character code” is “400” The “external character display information” can be converted into the association of the information “vector data C1”.

  (2-5) Then, after the conversion process of S204, the central processing server as the processing means 20 uses the character code converted by the conversion process of S204 based on the undefined character code DB 33 of the HDD as the storage means 30. The character code is converted into the character code in the character code system identification information included in the sentence transmission command received in S201 (S205). Here, description will be made assuming that the character code system identification information included in the text transmission command received in S201 is information representing “A company's character code system”.

  Specifically, S205 will be described. In S204, “character code of single character code system” of “1” is converted to “character code system identification information” by “single character code conversion DB 31 of FIG. Association of information that is “system” and “character code” is “50”, association of information that “character code system identification information” is “character code system of company B” and “character code” is “100”, “Character code system identification information” is “C character code system of C organization” and “character code” is “50”, and can be converted into association. In S205, the “character code system identification information” that is the character code in the “character code system of company A” that is the character code system identification information received in S201 is “the character code system of company A”. The information is converted into the association of information with the character code “50”. That is, among the associations of the information converted in S204, since the “character code system identification information” includes the association of information having the “character code system of company A”, the association of the information is selected.

  In S204, “character code of single character code system” of “2” is “character code system identification information” is “character code system of company A” by “single character code conversion DB 31 of FIG. It was possible to convert the code to “200” and “external character display information” to “vector data A1”. Again, among the associations of the information converted in S204, the association includes information in which “character code system identification information” is “A company's character code system”. Therefore, in S205, an association of information in which “character code system identification information” is “character code system of company A” and “character code” is “200” is selected.

  Furthermore, in S204, “character code of single character code system” of “3” is “character code system identification information” of “Company B's character code system” according to the single character code conversion DB 31 of FIG. Association of information in which “Code” is “300” and “External character display information” is “Vector data B1”, “Character code system identification information” is “Character code system of C organization”, and “Character code” is “400” ”And“ external character display information ”can be converted into information association“ vector data C1 ”. In this case, among the associations of the information converted in S204, the association of information whose “character code system identification information” is “A company's character code system” is not included. Therefore, it can be understood that the character represented by the “3” character code system of the single character code system is an undefined character (external character) in the “character code system of company A”. In this case, in this S205, the central processing server which is the processing means 20 is based on the undefined character code DB 33 of the HDD serving as the storage means 30, and the character code system identification information included in the text transmission command received in S201. Convert to character code in.

  Specifically, “Company A” is the character code system identification information included in the sentence transmission command received in S201 from the undefined character code DB 33 as shown in FIG. "Character code system" of "character code use presence / absence information" specifies "character code" with "unused". In the undefined character code DB 33 of FIG. 5, “Character code” of “500” is “Used” in “Character code system of Company A”, but “Character code” of “510” is “Not used”. I understand that there is. Therefore, in this case, “Character code” of “510” is selected, and “Character code use information” in “Character code” of “510” is changed to “Use” in the undefined character code DB 33 of FIG. The As a result, the central processing server which is the processing means 20 has “character code” of “510” in “character code system of company A” and “external character display information” of “vector data B1” or “vector data C1”. It will be converted to the association of information. By associating the “character code” of “510” that is undefined in the “character code system of company A” with the information of “external character display information” of “vector data B1” or “vector data C1”, Characters that are not defined in "Character Code System" can be displayed.

  Thus, in the conversion process in S204, if there is no character code in the character code system represented by the character code system identification information received in S201, the undefined data stored in the HDD serving as the storage means 30 in S205. Based on the character code DB 33, it is converted into an undefined character code in the input character code system identification information.

  (2-6) The conversion processing of S204 and S205 described above is performed character by character for the “character code of the single character code system” read from the sentence DB 32 of the HDD as the storage means 30 in S202. When the conversion processing of S204 and S205 is performed for all the characters of the read “character code of the single character code system”, the processing of S206 is performed based on the determination of S203.

  That is, the central processing server which is the processing means 20 transmits the sentence transmission command as communication data managed by the central processing server which is the processing means 20 with the association between the character code and the external character display information as text data. It transmits to an input means (11-13) (S206). As used herein, “communication means” refers to hardware that serves as a network interface such as a NIC.

(2-7) A display example of text data transmitted by the central processing server as the processing means 20 in S206 is shown in FIG. The “embedded font information” portion shown in the same figure includes the external character display information, and the “sentence” portion represents a sentence as a set of characters represented by the character code. The text data in FIG. 9 is SVG (Scaleable
In accordance with the (Vector Graphic) standard, fonts that include external characters and standardized characters that cannot be displayed by the general character code system used in the “text” part are converted to SVG in the “embedded font information” part. It is defined as vector data for display on a computer that complies with the standard. The “sentence” portion expresses the sentence data in the sentence data creation area in FIG. 8 in accordance with the SVG standard. As the internal data of this “sentence” part, only the character code is stored, and the external characters not defined in the character code system are the vector data defined in the “embedded font information” part. Based on this, characters are generated and displayed. The correspondence between the character code as the internal data of the “text” part and the vector data defined in the “embedded font information” part is associated by the tag “<glyph unicode =>”. In the “embedded font information” portion of the text data in accordance with the SVG standard in FIG. 9, the definition of the vector data of the external character of the ☆ mark and the definition of the vector data of the external character of the month mark are described as an example. .

  By embedding fonts with only external characters in SVG, characters defined in the character code system are usually displayed based on the character code as the internal data of the “sentence” part, and defined in the character code system. Non-external characters can be displayed 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”. Therefore, the same content can be displayed on a computer employing various character code systems. FIG. 10 shows an example in which the text data of FIG. 9 is displayed by a mobile phone or a personal computer compliant with the SVG standard. The mobile phone of Company A and Company B in FIG. 10 does not display the full text of the text data, but this is because the display of the mobile phone is small, and if the screen is scrolled left and right, the full text can be viewed. Can do.

  In the above description, it is assumed that the beauty-defined character code DB 33 as shown in FIG. 5 is stored in the HDD as the storage means 30. However, it is also possible to store undefined character codes in each character code system directly in the single character code conversion DB 31 as shown in FIG. 3 without using the beauty-defined character code DB 33 as shown in FIG. it can.
