U+11A08 "𑨈" Zanabazar Square Vowel Sign Au Unicode Character

U+11A08 "𑨈" Zanabazar Square Vowel Sign Au is a combining diacritical mark used in the Zanabazar Square script, an abugida historically employed for writing Tibetan, Sanskrit, and Mongolian. This specific sign represents the vowel sound "au" and is placed above the consonant letter to modify its inherent vowel, functioning as a dependent vowel marker rather than an independent character. The Zanabazar Square script, named after the 17th century Mongolian Buddhist monk and scholar Zanabazar, is known for its geometric letterforms and was designed to facilitate the transcription of Buddhist texts, though it saw limited historical use and is now recognized primarily for its linguistic and cultural significance.
