U+1DB7 "ᶷ" Modifier Letter Small Upsilon Unicode Character

U+1DB7 "ᶷ" Modifier Letter Small Upsilon is a diacritical mark derived from the Greek letter upsilon, represented as a superscript or modified version of the small upsilon glyph. It belongs to the Phonetic Extensions block and is used primarily in phonetic transcription, particularly within the International Phonetic Alphabet or related notation systems, to denote a secondary articulation or a specific vocalic quality such as a rounded close central vowel. This character functions as a spacing modifier, meaning it appears on its own rather than combining directly with another letter, and it is employed in linguistic studies to capture precise articulatory features of speech sounds.
