U+17A9 "ឩ" Khmer Independent Vowel Quu Unicode Character

U+17A9 "ឩ" Khmer Independent Vowel Quu is a character used in the Khmer script to represent a specific independent vowel sound, functioning as a standalone syllabic unit without requiring a consonant base. This character is distinct from dependent vowel marks, as it begins a syllable on its own and is traditionally employed in the Khmer language to indicate the long vowel sound "uu" in words, often appearing in formal or literary contexts. It belongs to the Khmer block in Unicode, supporting the writing system of Cambodia, where such independent vowels are integral for accurately representing native vocabulary and loanwords.
