U+AA91 "ꪑ" Tai Viet Letter High Nyo Unicode Character

U+AA91 "ꪑ" Tai Viet Letter High Nyo is a glyph used in the Tai Viet script, which is employed to write the Tai Dam, Tai Dón, and other Tai languages of Southeast Asia. This specific letter represents a high tone version of the "nyo" consonant sound, similar to the palatal nasal /ɲ/ found in English words like "canyon," and is distinguished from its low tone counterpart within the script's tonal orthography. It is encoded in the Unicode Standard as part of the Tai Viet block, which was added in version 5.2 to support the digital preservation and modern communication of these endangered Tai languages.
