Re: [ft] how to know if a font file contains a unicode character font?

[suzuki toshiya]

Hi,

Q1) The answer is dependent with how you define "language".
OpenType spec distinguish the script and language, I think
it's useful for you to clarify what you want to do, please
check.

Q2) In FT2 level, FT_Get_Char_Index() would be what you
can try, but, it does not guarantee that the glyph drawn
for given UTF32 codepoint is "a graphic that are differently
designed for each codepoint". I think using fontconfig is
easier solution, if you're working with Unix like systems.
