U+17B5 "឵" Khmer Vowel Inherent Aa Unicode Character

U+17B5 "឵" Khmer Vowel Inherent Aa is a combining mark used in the Khmer script to explicitly indicate the inherent vowel sound /aa/ that is already present by default in a consonant character. Unlike other Khmer vowel signs that visually attach to a consonant to alter its inherent vowel, this character functions as a visible diacritical marker, often applied for phonetic clarity, transliteration, or linguistic documentation to emphasize that a consonant carries its natural long vowel sound without modification.
