U+1D59 "ᵙ" Modifier Letter Small Sideways U Unicode Character

U+1D59 "ᵙ" Modifier Letter Small Sideways U is a small, rotated form of the Latin letter U that is primarily used in phonetic transcription, particularly within the Uralic Phonetic Alphabet (UPA), where it functions as a diacritic modifier to indicate a specific type of vowel quality or length. This character often represents a reduced, unstressed, or murmured vowel sound that is distinct from a full U, and its sideways orientation helps distinguish it from other phonetic symbols while maintaining visual continuity with related vowel markings. It is also found in some extended Latin character sets for orthographies of minority languages, where it denotes a highly centralized or obscured back vowel.
