U+1D99 "ᶙ" Latin Small Letter U with Retroflex Hook Unicode Character

Unicode Version 17.0

U+1D99 "ᶙ" Latin Small Letter U with Retroflex Hook is a phonetic symbol primarily used in linguistic transcriptions, particularly within the International Phonetic Alphabet extensions, to represent a retroflexed or rhotacized version of the vowel sound normally denoted by the letter "u." Its distinctive feature is the small hook attached to the bottom right of the standard Latin letter "u," which indicates articulation with the tongue curled back toward the palate. This character allows linguists and speech pathologists to precisely document specific vowel qualities found in some languages or dialects, such as certain varieties of Mandarin Chinese or retroflex vowels in some North American indigenous languages.
