U+1D55 "ᵕ" Modifier Letter Small Bottom Half O Unicode Character

U+1D55 "ᵕ" Modifier Letter Small Bottom Half O is a typographic symbol classified as a modifier letter, specifically based on the bottom half of a small Latin letter 'o'. It is used in phonetic transcription, particularly within the International Phonetic Alphabet and related systems, to indicate a diacritic-like modification of an adjacent character, such as denoting a lowered or a specific vowel quality. Unlike a full letter, this character functions as a spacing modifier, meaning it occupies its own horizontal space in text rather than combining directly with another letter, allowing it to be placed adjacent to base characters for precise phonetic or linguistic notation.
