U+D7B9 "ힹ" Hangul Jungseong Eu-A Unicode Character

U+D7B9 "ힹ" Hangul Jungseong Eu-A is a modern, but currently obsolete, vowel cluster from the Korean Hangul writing system. It represents a combination of the single vowel "eu" (ㅡ) and the diphthong "a" (ㅏ), forming a single compound vowel that was once used in historical or experimental varieties of Korean orthography but is not part of standard modern Korean. As one of the many Hangul syllables and jamo sequences encoded in Unicode, this character exists primarily to support historical texts, linguistic research, and the complete representation of the Korean script.
