U+0BCD "்" Tamil Sign Virama Unicode Character

U+0BCD "்" Tamil Sign Virama is a combining diacritical mark used in the Tamil script to indicate the suppression of the inherent vowel 'a' that is normally attached to a consonant, thereby creating a pure consonant or half-consonant form. It is visually represented as a small dot or superscript circle placed above or beside the base consonant character. This sign is essential for accurately writing Tamil, as it enables the representation of consonant clusters and dead consonants, which are common in the language's morphology and in borrowings from Sanskrit.
