U+A8B9 "ꢹ" Saurashtra Vowel Sign Uu Unicode Character

U+A8B9 "ꢹ" Saurashtra Vowel Sign Uu is used in the Saurashtra script, an abugida historically employed to write the Saurashtra language primarily in the Tamil Nadu region of India. This character functions as a combining diacritical mark that represents a long vowel sound, specifically the "ū" vowel as in "boot," and it is placed above the consonant letter it modifies to change its inherent vowel. The Saurashtra script is part of the Brahmic family and is encoded in the Unicode standard to support digital preservation and modern typesetting of this minority language, which has seen a revival in cultural and educational contexts.
