In this embodiment, the local terminal obtains a target text character and a font cache library, where the font cache library includes a mapping relationship between cached fonts and text characters. The local terminal obtains the target text character and obtains a font cache library used for searching a font corresponding to the target text character. Optionally, there may be at least two font cache libraries, where the at least two font cache libraries correspond to an application program respectively, for example, 5 application programs (including the application program 1 to the application program 5) are installed in the local terminal, and each application program corresponds to a font cache library respectively, that is, there are 5 font cache libraries, when the local terminal runs the application program 1, the local terminal needs to display text data in the application program 1, obtain the font cache library corresponding to the application program 1, and take each text character in the text data that the local terminal needs to display as a target text character in sequence, and different application programs correspond to different font cache libraries, so that the same text data can have different display effects for different application programs, so as to improve the diversity of character display effects, so that different application programs can have different display styles, thereby improving the individuation of different application programs; optionally, there may be a font cache library, when the local terminal needs to display the text data, each text character in the text data is sequentially used as a target text character to obtain the font cache library, when a plurality of application programs share one font cache library, a storage space used by the font cache library may be reduced, resources are saved, it is not necessary to search for a corresponding font cache library according to the application programs, and further, the efficiency of text display processing is improved, further, when the font cache library is stored in the local terminal, because the storage space used by the font cache library is reduced, thereby the operating efficiency of the local terminal may be improved.
The mapping relation between the cache fonts and the text characters in the font cache library is created through the relation between the text characters in the long history text data and the cache fonts, and the cache fonts refer to display fonts used when the text characters are displayed in the long history text data. Furthermore, historical long text data can be obtained, the historical long text data is traversed, and text characters and display fonts for displaying the text characters included in the historical long text data are obtained; and counting the use frequency of the display fonts, taking the display font with the maximum use frequency as a cache font of the text character, establishing a mapping relation between the text character and the cache font, and storing the mapping relation to a font cache library. When the display font comprises a font, the display font can be directly used as a cache font of the text character. Optionally, a mapping relationship preset manually may also be obtained, and the preset mapping relationship is added to the font cache library. The mapping relation contained in the font cache library represents that the cache font corresponding to the mapping relation supports the text character to be displayed, so that when the target cache font having the mapping relation with the target text character is found in the font cache library, the target cache font can be considered to support the target text character to be displayed, the font support relation between the target text character and the target cache font does not need to be detected, the time consumed for obtaining the font corresponding to the text character can be reduced, and the text display efficiency is improved.

Further, when the display line spacing is a multiple line spacing such as a single line spacing or a 1.15 line spacing, the local terminal may determine the line height according to the multiple line spacing and the character size, and determine the display line number in the display area based on the character display height and the line height. Similarly, the character display width may be determined according to the display width and the display margin, and the number of line display characters of each line in the display area may be determined according to the character display width, the first character display format of the paragraph, and the character size.

Optionally, the font support relationship includes a support display relationship and a matching failure relationship, where the support display relationship is used to represent that a default font can be supported, and a font support relationship between the default font and the default font is displayed for a text character in the support display relationship, for example, if the font support relationship between the default font 1 and the text character 1 is the support display relationship, the default font 1 may support the text character 1 to be displayed; the matching failure relationship is used for representing the text character, and when the default font with the font support relationship with the text character being the matching failure relationship is displayed, the display will fail, that is, the matching failure relationship is used for representing that the default font does not support the target text character to be displayed, for example, when the font support relationship between the default font 2 and the text character 2 is the matching failure relationship, if the text character 2 is displayed in the default font 2, the text character 2 cannot be normally displayed.
Further, the default font library comprises a first default font library; the first default font library is a font library having an initial association relation with the application system, and the initial association relation is a font library carried by the application system when the application system is installed on the local terminal. Optionally, the local terminal detects a font support relationship between a default font in the default font library and the target text character, acquires at least two first default fonts in the first default font library when the target default font corresponding to the target text character is acquired in the default font library according to the font support relationship, and acquires the font priority of each first default font; and sequentially detecting font support relations between the target text characters and at least two first default fonts based on the font priorities, setting the font support relations between the target text characters and the at least two first default fonts as the first default fonts supporting the display relations, and determining the font support relations as the target default fonts corresponding to the target text characters. Optionally, the local terminal obtains a font priority of each first default font in the first default font library, sorts each first default font based on the font priority, sequentially detects font support relationships between the target text character and at least two first default fonts based on the sorted first default fonts until the font support relationship between the target text character and the obtained first default font is the first default font supporting the display relationship, and determines the first default font as the target default font corresponding to the target text character.

Optionally, referring to fig. 6, fig. 6 is a schematic diagram of a character font matching process provided in the embodiment of the present application. As shown in fig. 6, the process includes the steps of:
step S602, detecting whether a target cache font corresponding to the target text character is traversed in the font cache library.
Optionally, the local terminal obtains the target text character, obtains the font cache library 601, traverses the font cache library 601, and detects whether a target cache font corresponding to the target text character is traversed in the font cache library 601, specifically referring to descriptions in step S301 to step S302 in fig. 3. If the target cache font corresponding to the target text character is traversed in the font cache library 601, determining the target cache font as the target display font of the target text character, specifically referring to the description in step S303 in fig. 3; if the target cache font corresponding to the target text character is not traversed in the font cache library 601, a first default font library 603 is obtained, and step S604 is executed.
Step S604, it is detected whether the font supporting relationship exists in the first default font library as the first default font supporting the display relationship.
Optionally, the local terminal detects at least two first default fonts in the first default font library, and sequentially detects font support relationships between the target text character and the at least two first default fonts. If the font support relationship in the first default font library is a first default font supporting the display relationship, determining the first default font as a target default font corresponding to the target text character, and taking the target default font as the target display font of the target text character; if the font support relationships between the at least two first default fonts and the target text characters in the first default font library are all matching failure relationships, step S605 is executed. For the step, reference may be made to the detailed description shown in step S304 in fig. 3, which is not described herein again.
Step S605, a character type to which the target text character belongs is acquired.
Optionally, the local terminal may obtain a character type to which the target text character belongs. If the character type belongs to the first character type, acquiring a second default font library 606, acquiring a second default font, of which the font support relationship with the target text character is the support display relationship, from the second default font library 606, as a target default font corresponding to the target text character, and taking the target default font as the target display font of the target text character; if the character type belongs to the second character type, a third default font library 607 is obtained, and step S608 is executed.
Step S608, detecting whether a mapping relationship associated with the character type to which the target text character belongs exists in the third default font library.
Optionally, if it is detected that a mapping relationship associated with the character type to which the target text character belongs exists in the third default font library 607, taking the third default font in the mapping relationship associated with the character type to which the target text character belongs as the target default font of the target text character, and determining the target default font as the target display font of the target text character; if it is detected that the mapping relationship associated with the character type to which the target text character belongs does not exist in the third default font library 607, the target default font corresponding to the target text character is acquired from the second default font library 606, and the target default font is determined as the target display font of the target text character. The second default font library includes all fonts in the application system, and therefore, fonts supporting the target text character can be found through the second default font library.
Further, a target mapping relationship between the target default font and the target text character may be established, and the target mapping relationship is added to the font cache library. Since the number of the types of the text characters included in the text data to be displayed by the local terminal is small, the font cache library stores the displayed text characters and the mapping relationship between the fonts used by the text characters, which occupies a small memory space.
Further, the local terminal may render the target text character based on the target display font. Optionally, acquiring a display position of the first character in the display area, and rendering the target text character in the display area according to the display position of the first character and the target display font; the first character display position is determined based on the size information, the display margin, and the first character display format of the paragraph. Optionally, when the target text character is rendered in the display area according to the first character display position and the target display font, the local terminal obtains a text position of the target text character in the text to be displayed, and determines a target character display position of the target text character in the display area according to the first character display position and the text position; at the target character display position, the target text character is rendered based on the target display font.
Optionally, when the local terminal is displaying text data and needs to update the currently displayed text data, the local terminal may obtain a rendered text and a text update area displayed in the display area, and determine the display position of the initial character according to the text update area and the rendered text, where the text update area is determined according to a text update request obtained by the local terminal. When the text updating request is used for indicating to view the rendered text, the local terminal directly obtains text data requested to be viewed by the user in the rendered text according to the text updating request, and displays the text data requested to be viewed by the user in the display area. When the text updating request is used for indicating to view unrendered text, the local terminal can determine a text updating area according to the text updating request, determine a display position of the first character based on the text updating area, and determine an initial rendering position of the character according to the rendered text; the method comprises the steps of starting at a character initial rendering position in text data, sequentially acquiring text characters as target text characters, executing the step of acquiring a target display font of the target text characters in the application, determining a target character display position of the target text characters according to the first character display position, and rendering the target text characters based on the target display font at the target character display position of a display area.
The method comprises the steps of obtaining long text data to be displayed, obtaining target text characters in the long text data, and obtaining a font cache library, wherein the font cache library comprises a mapping relation between cache fonts and the text characters; traversing the font cache library according to the target text characters and the mapping relation; if the target cache font corresponding to the target text character is traversed in the font cache library, taking the target cache font as a target display font for rendering the target text character; if the target cache font corresponding to the target text character is not traversed in the font cache library, acquiring a default font library, detecting a font support relation between the default font in the default font library and the target text character, acquiring the target default font corresponding to the target text character in the default font library according to the font support relation, and taking the target default font as a target display font for rendering the target text character. Through the process, the font corresponding to the target text character is acquired, wherein the time required for acquiring the font corresponding to the target text character through the font cache library is short, so that the time consumed for acquiring the font corresponding to the text character can be reduced when text data is displayed through the text display method and the text display processing efficiency is improved. Meanwhile, the time consumed by text display processing is reduced, so that the fluency of text data display is improved. And moreover, fonts corresponding to the target text characters are searched from the default font libraries in sequence, the fonts contained in different default font libraries are not identical, and the efficiency of text display processing can be improved through the sequence matching sequence of the different default font libraries.
