Even if you do the above with target="pattern", the result from FcFontSort() may contains patterns not matching lang="ko". it really depends on other recipes. it is just building better patterns against recipes on your box. You need to call FcFontRenderPrepare() to evaluate target="font" and finalize to get the result of better fonts against your query, or just call FcFontMatch(). > So I guess my questions are: > > What's wrong with the fonts.conf lang "ko" section? > Why does 'fs' contains all these fonts, even though we pass FC_LANG of "ko"? > Why is NewHDB returned in 'match', even though NewHDR is the only one listed in this section? > > Many Thanks, sorry for all the questions! :) > Derek > > _______________________________________________ > Fontconfig mailing list > Fontconfig@xxxxxxxxxxxxxxxxxxxxx > http://lists.freedesktop.org/mailman/listinfo/fontconfig HTH, -- Akira TAGOH _______________________________________________ Fontconfig mailing list Fontconfig@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/fontconfig
