The General Alphabet of Cameroon Languages is an orthographic system created in the late 1970s for all Cameroonian languages.[1][2] Consonant and vowel letters are not to contain diacritics, though ⟨ẅ⟩ is a temporary exception. The alphabet is not used sufficiently for the one unique letter, a bilabial trill, to have been added to Unicode.
Maurice Tadadjeu and Etienne Sadembouo were central to this effort.
