U+01DA "ǚ" Latin Small Letter U with Diaeresis and Caron Unicode Character
Unicode Version 17.0
ǚ
U+01DA "ǚ" Latin Small Letter U with Diaeresis and Caron is a composite glyph used primarily in the Pinyin romanization system for Mandarin Chinese to represent the third tone (falling-rising tone) on the vowel sound ü, which is itself a close front rounded vowel. The diaeresis, or two dots above the letter, indicates that the u should be pronounced as a separate vowel rather than as part of a diphthong, most commonly occurring after the consonants l and n. The caron, or háček, placed above the diaeresis, specifically marks the third tone contour, making this character essential for accurately writing and pronouncing certain Chinese syllables like lǚ and nǚ in standard Pinyin.
