U+A8C1 "ꣁ" Saurashtra Vowel Sign O Unicode Character

U+A8C1 "ꣁ" Saurashtra Vowel Sign O is a combining diacritical mark used in the Saurashtra script, which is historically employed to write the Saurashtra language primarily in the Tamil Nadu region of India. This character functions as a vowel sign that attaches to a consonant base character to modify its inherent vowel sound, specifically indicating the long "O" vowel. It belongs to the Saurashtra block of Unicode and is positioned after the consonant symbol it modifies, reflecting the typical abugida structure of the script where vowel signs are written as dependent marks. In modern usage, this character supports the orthographic representation of the Saurashtra language for both traditional texts and contemporary digital communication.
