U+0B83 "ஃ" Tamil Sign Visarga Unicode Character

U+0B83 "ஃ" Tamil Sign Visarga is a special diacritic in the Tamil script, distinct from the usual vowel and consonant signs, and is used to represent a voiceless glottal fricative sound similar to the final 'h' in English words like "ah" or "oh". It appears after a Tamil vowel to indicate a short, independent breathy release, often transcribed with the letter 'h', and is primarily employed in transliterating foreign words, Sanskrit loanwords, or in poetic and formal contexts to denote this specific phonetic nuance.
