In fontconfig.h, the “lang” property is listed as follows: #define FC_LANG "lang" /* String RFC 3066 langs */ this would seem to indicate that the value is supposed to be a string. I just discovered, in running a test with my python_fontconfig binding <https://github.com/ldo/python_fontconfig/>, that in fact this property value is an FcLangSet. Does this apply to the other properties with “lang” in their name as well? _______________________________________________ Fontconfig mailing list Fontconfig@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/fontconfig
