U+1A69 "ᩩ" Tai Tham Vowel Sign U Unicode Character

Unicode Version 17.0

U+1A69 "ᩩ" Tai Tham Vowel Sign U is a combining diacritical mark used in the Tai Tham script, which is historically employed for writing languages such as Northern Thai (Kam Mueang), Tai Lü, and Khün. This vowel sign represents the sound /u/ and is positioned below a consonant character to alter its inherent vowel, forming a closed syllable with a short u sound. As part of the Tai Tham block in Unicode, it supports the preservation and digital use of this traditional script, which features distinct rounded letterforms and is still utilized in religious and cultural contexts in parts of Southeast Asia, particularly in northern Thailand, Laos, and Myanmar.
