Hello Akira,

Thank you for your advice.

Main issue is that my japanese font file doesn't have "ja".
Below is lang info of japanese font file.
So I can't find japanese font using lang info("ja") of font file.

Maybe other two-character specify japanese font file?
Or my japanese font file has wrong lang info?

Best Regards,
Deokjin Kim

bg is Bulgarian, ko is Korean, kum is Kumyk, os is Ossetian, ru is
Russian, sel is Selkup.

That would means that font has glyphs those orthography files contains.

I think you need to add the lang into your pattern like:

FcPatternAddString(pat, FC_LANG, "ko");
