U+0BCA "ொ" Tamil Vowel Sign O Unicode Character

Unicode Version 17.0

U+0BCA "ொ" Tamil Vowel Sign O is a combining diacritical mark used in the Tamil script to represent the independent vowel sound "o" when it modifies a consonant. This character is classified as a dependent vowel sign, meaning it is placed after a consonant character to indicate that the consonant is pronounced with the vowel "o" following it, altering the inherent "a" sound of the consonant. In typographic context, the sign appears as a visually distinct ligature that combines a curve and a short vertical line above and to the right of the base consonant, and it is encoded in the Unicode standard under the Tamil block, specifically for writing the Tamil language where it is an essential component for accurate phonetic representation.
