U+11A7 "ᆧ" Hangul Jungseong O-Yae Unicode Character

U+11A7 "ᆧ" Hangul Jungseong O-Yae is a highly rare and largely obsolete vowel glyph from the Hangul writing system, representing a medial vowel sound that combines elements of "o" and "yae" as part of the Korean language's historical orthography. This character was used in early or experimental forms of Hangul to denote a specific diphthong sound that has since fallen out of standard modern usage, making it a largely historical or typographic curiosity rather than a practical character. Its inclusion in Unicode ensures that archival texts, linguistic studies, and specialized digital fonts can faithfully reproduce this archaic phoneme without corruption.
