Has anyone ever tried to compute the ascent and descent for Latin characters? I.e. 'A' to 'Z' and 'a' to 'z'?
The reason I am asking this is that all metrics I have come across are defined on _all_ glyphs in a given font file. Apparently their values are greater than those of Latin characters because western fonts usually include characters like Å and ş. The only exception I could find are os2.usWinAscent and os2.usWinDescent, which are still defined to include characters in the Windows ANSI character set. Does FreeType provide a standard 'cunning' way to compute metrics for Latin-only characters? If not what would be the best way to do it? Another (unrelated) question: what is "AFM file" as mentioned in os2.sTypoAscender and os2.sTypoDescender documentation? Any help would be much appreciated. Anson
