U+1134C "𑍌" Grantha Vowel Sign Au Unicode Character

U+1134C "𑍌" Grantha Vowel Sign Au is a combining diacritical mark used in the Grantha script, an ancient Brahmic writing system historically employed in South India for writing Sanskrit, Tamil, and Manipravalam. This vowel sign represents the long diphthong sound "au" and is typically placed above or attached to a consonant character to modify its inherent vowel, creating the corresponding "au" syllable. It is part of the Grantha block in Unicode, which was added to support the digital representation of classical and liturgical texts, particularly those from Tamil and Hindu religious traditions.
