U+0BC2 "ூ" Tamil Vowel Sign Uu Unicode Character

U+0BC2 "ூ" Tamil Vowel Sign Uu is a combining diacritical mark used in the Tamil abugida to represent the long vowel sound "Uu" (as in "boot"). It visually appears as a curved loop or hook above the consonant letter it modifies, extending the inherent short vowel "u" to a longer duration. This character belongs to the Tamil script block and is strictly classified as a combining mark, meaning it must be typed after a base Tamil consonant character, such as க (ka), to form a complex syllable like கூ (kuu). Proper font support is required to ensure the diacritic correctly positions above the base letter, as its rendering is essential for accurate reading and writing in Tamil.
