--- Comment #4 from Nguyen Chinh Huu huupoke12@gmail.com --- So I don't think this problem can be solved in that way (creating new glyphs). The program doesn't have a static character set, mostly of it is user-generated content (chat, metadata (names)...).
So I think that we should re-use existing fonts. There are many high quality font licensed under SIL Open font license, so if they are incompatible with LGPL, then we should make a separate package for it (like wine-gecko and wine-mono). But I think that the SIL license is only applied to those fonts, not the application comes with those font. And if that still not possible, then we should make the system responsible of rendering the missing glyphs (fontconfig just find the installed fonts for the glyphs). And by the way, I see GNU FreeFont is under GPL but it's v3, I don't think it compatible with v2.
