Judson is a serif font created for African literacy. It consists of as lots of glyphs and precomposed combinations that I know of for all African languages written in Latin-derived alphabets. It utilizes OpenType tables for right placement of diacritical marks, including stacked marks. Care has been taken so that all characters are conveniently distinguished, even in the italic face. The medium roman face has assistance for the International Phonetic Alphabet (IPA.)
