U+1EAF "ắ" Latin Small Letter A with Breve and Acute Unicode Character
Unicode Version 17.0
ắ
U+1EAF "ắ" Latin Small Letter A with Breve and Acute is a precomposed character used in the Vietnamese alphabet to represent a specific tonal variant of the vowel "a." It combines a Latin small letter "a" with a breve diacritic above it, which indicates a short vowel sound, and an acute accent, which marks the rising or "sắc" tone in Vietnamese. This character is part of the Latin Extended Additional block and is typically employed in written Vietnamese to distinguish meaning between words that would otherwise be homographs, such as in the word "mắ" (a type of fish sauce). Its inclusion in Unicode ensures proper digital representation and text processing for languages that require this precise diacritic combination.
