U+AA98 "ꪘ" Tai Viet Letter Low No Unicode Character

U+AA98 "ꪘ" Tai Viet Letter Low No is a character used in the Tai Viet script, which is employed to write several Tai languages, including Tai Dam, Tai Don, and Thai Song, primarily in Vietnam, Laos, and China. This specific letter represents a low-register consonant sound, akin to the English "n," and is part of a complex system where tone is conveyed through diacritical marks rather than the letter itself. It serves as a key component in preserving and writing the linguistic heritage of Tai-speaking communities, who traditionally recorded their languages using this distinctive script before modern standardized encoding.
