U+1E6F3 "𞛳" Tai Yo Letter At Unicode Character

U+1E6F3 "𞛳" Tai Yo Letter At is a relatively recent addition to the Unicode Standard, encoded as part of the Tai Yo script block which was introduced in version 15.0 in 2022. This character specifically represents the consonant sound "at" in the Tai Yo language, a Tai-Kadai language spoken by a small population primarily in the Nghệ An and Thanh Hóa provinces of Vietnam. The character is notable for its distinctive curved and angular strokes. Its inclusion in Unicode ensures that the Tai Yo language can be written and preserved in digital environments, supporting the documentation and revitalization of this endangered linguistic heritage.
