Fontconfig - Mar 2012 - How can I get font list for specific language?

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.
     
lang=bg|fj|ho|ia|ie|io|kum|nr|om|os|ru|sel|so|ss|st|sw|ts|uz|xh|zu|kj|kwm|ms|ng|rn|rw|sn|za
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");

That is because your font just doesn''t satisfy the requirements of
ja.orth. you can check what glyphs are really missing in the font.

I did write a small tool to do that some while ago.  I don''t know if
it still works and need to rewrite it according to some advice but
anyway. see https://bugs.freedesktop.org/show_bug.cgi?id=29312
