It is certainly the case that in the Yoruba alphabet "gb" is a distinct unit - the term we use for that is "grapheme" (i.e. "a", "b", "gb" are all Yoruba graphemes). But Unicode does not encode graphemes; it encodes the characters that comprise graphemes. If "gb" needs distinct processing in software, then software can handle that, even if it is represented in the encoding as a sequence < g, b > This is no different from e.g. the "ch" and "ll" digraphs in Spanish. The Spanish alphabet has A B C CH D ... K L LL M ... Software is able to support this even though the CH and LL are encoded as sequences, < c, h > and < l, l >. Peter Constable
