U+17B4 "឴" Khmer Vowel Inherent Aq Unicode Character

U+17B4 "឴" Khmer Vowel Inherent Aq is a mark used in the Khmer script to explicitly denote the inherent vowel sound /ɑ/ (often transliterated as "a" or "â") that is normally unwritten when a consonant stands alone. This character is part of the Khmer block and serves a specific orthographic purpose, allowing writers to indicate the default vowel pronunciation in cases where it might be ambiguous or where the standard inherent vowel is not contextually clear. It is considered a combining character and is not used in everyday modern Khmer but rather in specialized linguistic or historical contexts.
