U+0186 "Ɔ" Latin Capital Letter Open O Unicode Character

U+0186 "Ɔ" Latin Capital Letter Open O is a letter used primarily in the African reference alphabet and in the orthographies of several African languages, such as Ewe, Fon, and Gen, where it represents an open-mid back rounded vowel sound, similar to the vowel in the English word "caught" or the "o" in "hot" in some dialects. It visually resembles a reversed capital letter C, reflecting its status as the uppercase counterpart to the lowercase "ɔ" (U+0254). This character is also utilized in the International Phonetic Alphabet and in certain linguistic transcriptions to denote the same vowel quality, distinguishing it from the closer "o" sound represented by the standard Latin O.
