U+019F "Ɵ" Latin Capital Letter O with Middle Tilde Unicode Character
Unicode Version 17.0
Ɵ
U+019F "Ɵ" Latin Capital Letter O with Middle Tilde is a modified version of the letter O that features a tilde or wavy line placed horizontally through its center, rather than above it. This character is primarily used in certain African languages, such as the Gbari language of Nigeria, where it represents a distinct vowel sound, often a close-mid central rounded vowel. In the International Phonetic Alphabet, a similar symbol is used to denote the same phonetic value, although the Unicode version is specifically intended for orthographic use in written languages. Its design distinguishes it from the standard O by adding a diacritic that modifies the vowel's pronunciation for linguistic accuracy.
