U+1A73 "ᩳ" Tai Tham Vowel Sign Oa Above Unicode Character

Unicode Version 17.0

U+1A73 "ᩳ" Tai Tham Vowel Sign Oa Above is a combining diacritical mark used in the Tai Tham script, an abugida traditionally employed for writing languages such as Northern Thai (Lan Na), Tai Lü, and Khün. This character is placed above a consonant to modify its inherent vowel sound, specifically indicating the long vowel "oa," which distinguishes it from other vowel signs in the script. As a combining mark, it does not stand alone but is visually positioned above the base consonant, blending into the script’s distinctive, curved calligraphic style. Its inclusion in Unicode facilitates digital representation and preservation of these regional languages, supporting linguistic documentation and modern communication in communities that use the Tai Tham writing system.
