U+A7B7 Latin Small Letter Omega

The Wikipedia has the following information about this codepoint:

Latin omega, or simply omega, is an additional letter of the Latin alphabet, based on the lowercase shape of the Greek letter omega ⟨ω⟩. It was included as a Latin letter in the Mann and Dalby 1982 revision of the African reference alphabet and has been used as such in some publications in the Kulango languages in Côte d'Ivoire in the 1990s. In other Kulango publications the letters V with hook ⟨Ʋ⟩ or Latin upsilon ⟨Ʊ⟩ are found instead. The Italian humanist Giovan Giωrgio Trissino proposed in 1524 a reform of Italian orthography that included lowercase and uppercase omega for the open ⟨o⟩ sound ([ɔ]). He later re-assigned it to the closed ⟨o⟩ ([o]).
