U+11C3B "𑰻" Bhaiksuki Vowel Sign Au Unicode Character

U+11C3B "𑰻" Bhaiksuki Vowel Sign Au is a combining diacritical mark used in the Bhaiksuki script, an ancient Brahmi-derived writing system historically employed to write Sanskrit and possibly other languages in regions of present-day India and Nepal. This vowel sign represents the diphthong "au" and is attached to the base consonant character to modify its inherent vowel sound, following the standard abugida structure of the script. The Bhaiksuki script, which dates to around the 11th to 12th centuries, is closely related to other northeast Indian scripts, and this particular vowel sign is encoded in Unicode's Bhaiksuki block, which was added to the standard in version 9.0 in 2016 to support scholarly and digital preservation of this historic writing system.
