Hi, We have two values in spacing property to consider if a font is monospaced or not. FC_MONO and FC_DUAL. Right now fontconfig decides it when: - single advance value available in a font -> FC_MONO - two advance values available in a font and larger value is twice of smaller value -> FC_DUAL This code worked for fonts which has smaller language coverage and satisfy older Unicode specifications that non-Latin characters assumes double-widths or so. Nowadays, various glyphs are included in even monospaced fonts which doesn't meet the above criteria (i.e. Noto Mono). it may be a time to update and improve this. What do you think? I'm not sure what approach is better though, the idea that comes to my mind is to refer sFamilyClass and Panose values in OS2 table. if there are any better idea or opposed to this, please let me know. BTW given that we decide it like that, it isn't DUAL anymore. need a good name for that too perhaps, but anyway.
