U+0981 "ঁ" Bengali Sign Candrabindu Unicode Character

U+0981 "ঁ" Bengali Sign Candrabindu is a combining diacritical mark used in the Bengali script and related South Asian writing systems, such as Assamese. It appears as a small crescent moon with a dot above it, positioned over a base character, and primarily indicates the nasalization of the vowel sound it modifies, changing the pronunciation to a nasal tone. Unlike the anusvara, which represents a pure nasal consonant, the candrabindu specifically nasalizes a preceding vowel, making it distinct in phonological function. This character is essential for accurately writing words like "চাঁদ" (chãd, meaning moon) and is part of the wider Brahmic family of scripts.
