U+A8BA "ꢺ" Saurashtra Vowel Sign Vocalic R Unicode Character

U+A8BA "ꢺ" Saurashtra Vowel Sign Vocalic R is a diacritical mark used in the Saurashtra script, which is historically employed to write the Saurashtra language, primarily in the Indian state of Tamil Nadu. This specific character functions as a vowel sign, representing a vocalic r sound, a syllabic consonant that appears in the language's orthography. Unlike an independent vowel letter, it attaches to a base consonant character to modify its pronunciation, forming a distinct syllabic nucleus. As part of the Saurashtra block in Unicode, this sign helps preserve and digitally represent the unique phonetic features of the Saurashtra writing system, which has seen revitalization efforts in modern times.
