I'm planning to add Greek and Cyrillic support to the font I'm developing. My question is: which glyphs must I add? Unicode tables have archaic letters and additional signs I suppose are not necessary (at least, not all of them).
What I think to add:
This is enough? Am I missing something?
Besides this, I'd like to know about serif fonts with good design for Greek and Ciryllic alphabets. I believe Minion is one of these, but it would be great to have others to analyse and research their typographical solutions for non-Latin glyphs.
