U+1EA2 "Ả" Latin Capital Letter A with Hook Above Unicode Character
Unicode Version 17.0
Ả
U+1EA2 "Ả" Latin Capital Letter A with Hook Above is a grapheme used primarily in the Vietnamese alphabet, where the hook above diacritic indicates a low, rising-falling tone known as the hỏi tone. This tone is phonetically characterized by a slight dip in pitch followed by a rise, and the character appears in romanized Vietnamese as the capital form of the letter "a" bearing this mark. Its inclusion in Unicode ensures proper digital representation and text processing for the Vietnamese language, distinguishing it from similar characters like the standard Latin "A" or other diacritic variants.
