I'm working on a font which is already largely kerned, using table-based kerning. The main problem, besides the inefficiency with regards to the storage of the kerning of accented glyphs (with which I am not hugely concerned) is that there are many accented glyphs which are not kerned like their base glyphs. This is an obvious use-case for class-based kerning. Right now, I have tried to redo the kerning manually in a class-based fashion in FontForge (this font is developed in FontForge). This, however, is tedious, and if possible, I'd like to avoid it. Is there any way to automatically convert a font's kerning from a table to class-based kerning? (I am willing to have it begin by naïvely putting /A and /Aacute in different classes, etc.; I'd just like to be able to import the pair-based kerning into a class-based kerning feature so I can edit it as classes in FontForge). I would strongly prefer a free and open-source solution for this problem if one exists, but I am happy to hear all suggestions. I've scoured the web for some guidance, but my Google-fu didn't provide me with any solid answers (though I did see some mentions of this problem). Anybody have any tips?
