U+1EEC "Ử" Latin Capital Letter U with Horn and Hook Above Unicode Character
Unicode Version 17.0
Ử
U+1EEC "Ử" Latin Capital Letter U with Horn and Hook Above is a specialized glyph used in the Vietnamese alphabet to represent a specific vowel sound, combining the base letter U with two diacritical marks: a horn added to the right side of the letter, which indicates a distinct vowel quality, and a hook above, which marks the hỏi tone (a mid-low, dipping tone). This character is primarily employed in the romanized writing system of Vietnamese (Quốc Ngữ) to accurately transcribe tonal and phonetic distinctions essential to the language, such as in words like "cửa" (door). It is encoded in the Unicode standard under the Latin Extended Additional block, ensuring proper digital representation and processing for Vietnamese text.
