Unicode Version 17.0
ẳ
U+1EB3 "ẳ" Latin Small Letter A with Breve and Hook Above is a specialized Latin script glyph used primarily in the Vietnamese language to represent a specific tonal inflection of the vowel 'a'. This character combines a base Latin small letter 'a' with a breve diacritic, which indicates a short vowel sound, and a hook above, which signifies the hỏi tone, a mid-low, falling-rising tone in Vietnamese phonology. It is part of the Latin Extended Additional block in Unicode and is employed in romanized Vietnamese writing to accurately distinguish this tone from other tonal variations, such as the rising or flat tones, ensuring correct pronunciation and meaning in written text.
