Hi, Recently, fontconfig developers are discussing how to evaluate "is this font supporting 'emoji' set sufficiently?". Is it possible to design a subset of emoji to serve common use of emoji?
For detail about the discussion of fontconfig developers, please refer the thread from: https://lists.freedesktop.org/archives/fontconfig/2016-September/005830.html * about fontconfig fontconfig is a library which is widely used by Unix-like operating systems to locate a (pathname of) font file, by the query with a few typographic category (serif/sans-serif/monospace etc), script, and language. fontconfig crawls the font files on the systems, and make a database to respond such query. To guess the supported script and language, basically fontconfig checks the coverage of the codepoints with relevant glyph data. The coverage is compared with the orthography database: for the case of CJK script, the coverage is compared with GB 2312, Big5, HKSCS, JIS X 0208, KS X 1001 etc. * emoji and fontconfig At present, fontconfig developers are wondering how they can list the codepoints to evaluate the query "this font support emoji?". The stable subset of emoji would be the repertoire used by Japanese legacy cellular phones, but (personally) I don't think it is still respected to design some emoji fonts, as far as the developer is careful about the legacy cellular phone users. Is it possible to design a subset of emoji to serve common use of emoji? Or, if such attempt (evaluate the support level of emoji by checking some codepoints) is wrong, is there any good method to evaluate the support level of emoji in given font? Regards, mpsuzuki
