U+1EA5 "ấ" Latin Small Letter A with Circumflex and Acute Unicode Character
Unicode Version 17.0
ấ
U+1EA5 "ấ" Latin Small Letter A with Circumflex and Acute is a precomposed character used primarily in the Vietnamese alphabet to represent a specific tonal variant of the vowel "â." It combines a base Latin small letter "a" with a circumflex accent (^), which marks the vowel quality as a close central unrounded sound, and an acute tone mark (´), which indicates a high, rising tone in Vietnamese. This character is encoded in the Unicode Latin Extended Additional block and is commonly employed in Romanized Vietnamese writing to distinguish lexical meaning and pronunciation, as in the word "ấm" meaning warm.
