U+1EF3 "ỳ" Latin Small Letter Y with Grave Unicode Character
Unicode Version 17.0
ỳ
U+1EF3 "ỳ" Latin Small Letter Y with Grave is a precomposed character used primarily in the Vietnamese alphabet, where it represents the letter Y with a grave accent tone mark indicating a low, breathy or falling intonation in certain dialects. It is also occasionally employed in linguistic transcriptions or older English orthographies to denote a stressed or distinctively accented Y. The character is formed by combining the base Latin small letter Y with a combining grave accent, though Unicode encodes it as a single entity for compatibility with legacy systems. Its uppercase counterpart is U+1EF2 "Ỳ", and it belongs to the Latin Extended Additional block, supporting the accurate representation of tonal languages in digital text.
