U+09C4 "ৄ" Bengali Vowel Sign Vocalic Rr Unicode Character

U+09C4 "ৄ" Bengali Vowel Sign Vocalic Rr is a combining diacritic mark used in the Bengali script to represent a specific vowel sound. This character is an extended vocalic R, often employed in transliterating Sanskrit terms into Bengali, where it modifies the preceding consonant to include a lengthened or retroflex vocalic "r" sound, similar to the Sanskrit ऋ (vocalic R) but with a longer duration. As a vowel sign, it does not appear independently but attaches to a consonant base, and its usage is primarily historical or in scholarly contexts rather than in common modern Bengali writing.
