U+113B8 "𑎸" Tulu-Tigalari Vowel Sign Aa Unicode Character

U+113B8 "𑎸" Tulu-Tigalari Vowel Sign Aa is a combining diacritic mark used in the Tulu-Tigalari script, a historically significant abugida primarily employed to write the Tulu language of coastal Karnataka and Kerala, India. This specific vowel sign represents the long "aa" sound and is placed after a consonant character to modify its inherent vowel, extending the pronunciation. It functions as a dependent vowel sign, meaning it cannot stand alone and must attach to a base consonant letter to form a complete syllable. The inclusion of this character in the Unicode Standard ensures proper digital representation and preservation of the Tulu-Tigalari script, supporting efforts to document and revitalize the Tulu language.
