U+0B86 "ஆ" Tamil Letter Aa Unicode Character

U+0B86 "ஆ" Tamil Letter Aa is a vowel in the Tamil script, representing the long "aa" sound, as in the English word "father." It is the second character in the Tamil syllabary and is distinct from the short vowel "அ" (a). In Tamil orthography, this character can appear as an independent vowel at the beginning of a word or as a vowel sign (a diacritic mark) attached to a consonant to modify its inherent vowel sound. It is widely used in classical and modern Tamil literature, as well as in everyday writing, to form words such as "ஆறு" (aaru, meaning river) and "ஆசை" (aasai, meaning desire).
