U+A8BB "ꢻ" Saurashtra Vowel Sign Vocalic Rr Unicode Character

U+A8BB "ꢻ" Saurashtra Vowel Sign Vocalic Rr is a combining diacritical mark used in the Saurashtra script, an abugida historically employed to write the Saurashtra language spoken in parts of Tamil Nadu, India. This specific vowel sign represents a vocalic retroflex lateral flap, a syllabic consonant sound akin to a vowel-like "rr" or "ṛ", and is attached to a consonant base character to indicate that the following "vocalic r" follows the consonant, altering pronunciation without an inherent vowel. As part of the Saurashtra block, it helps preserve a unique phonetic feature not found in many other Brahmic scripts, and it appears alongside other vowel signs in texts related to Saurashtra literature and inscriptions.
