U+0BC8 "ை" Tamil Vowel Sign Ai Unicode Character

U+0BC8 "ை" Tamil Vowel Sign Ai is a combining diacritical mark used in the Tamil script to represent the long vowel sound "ai," functioning as a dependent vowel sign that attaches to a preceding consonant character to modify its inherent vowel sound. This character is part of the Tamil block within Unicode and is employed in writing many common Tamil words, such as "மை" (mai, meaning ink) or "பை" (pai, meaning bag). It appears as a distinct combining mark placed before the consonant glyph, visually resembling two short strokes or a small loop above the character in typical Tamil typography.
