U+D7B1 "ힱ" Hangul Jungseong O-O-I Unicode Character
Unicode Version 17.0
ힱ
U+D7B1 "ힱ" Hangul Jungseong O-O-I is a rarely used modern Hangul vowel character representing a triphthong sound that combines the elements ㅗ (o), ㅗ (o), and ㅣ (i) to form a complex syllable nucleus. Unlike standard Korean vowels, this character is part of the Unicode Hangul Syllables block but is not employed in contemporary Korean orthography or everyday language, serving instead as a typographical or historical curiosity within the Unicode standard for encoding obsolete or theoretical constructs. Its inclusion ensures that all possible vowel combinations in the Hangul writing system have a digital representation.
