U+0254 "ɔ" Latin Small Letter Open O Unicode Character

U+0254 "ɔ" Latin Small Letter Open O is a vowel symbol used in the International Phonetic Alphabet to represent the open-mid back rounded vowel sound, as in the British English pronunciation of "thought" or the vowel in the French word "porte". It is also employed in the orthographies of several African languages, such as Ewe and Yoruba, where it functions as a distinct letter in the alphabet. Visually, the character resembles a reversed lowercase "c" with a rounded top, distinguishing it from the similar-looking Latin small letter "c" or the Greek omicron. This glyph is part of the Latin Extended-B block in Unicode and is commonly used in linguistic transcription to indicate a specific vocalic quality.
