Why fonts are not included

This project does not ship proprietary font files such as Arial, Times New Roman, Microsoft YaHei, or SimSun. These fonts are subject to copyright restrictions. Font name references remain in the configuration for document compatibility, but the actual files have been removed to comply with open-source licensing.

Adding fonts

Font files go in public/fonts/ and must be named by their numeric index in the __fonts_files array in public/sdkjs/common/AllFonts.js.

Example: Adding Arial

  1. Open AllFonts.js and find the index for Arial regular — it is 223
  2. Place your font file at public/fonts/223 (no extension)
  3. The app loads it automatically when index 223 is requested

Other Arial variants:

VariantIndexPath
Regular223public/fonts/223
Italic224public/fonts/224
Bold226public/fonts/226
Bold Italic225public/fonts/225

To find the index for any font, look up its entry in the __fonts_infos array in AllFonts.js.

Only use open-source fonts or fonts you have a valid license for.
