U+1186 "ᆆ" Hangul Jungseong Yo-Yeo Unicode Character

U+1186 "ᆆ" Hangul Jungseong Yo-Yeo is a modern Hangul jamo representing a composite vowel sound, formed by combining the elements of "yo" (ㅛ) and "yeo" (ㅕ) to indicate a gliding diphthong from a medial rounded pronunciation to a more open fronted one. This character is primarily used in the Korean writing system as a jungseong, or medial vowel, within a syllabic block, where it attaches vertically to an initial consonant. Although it appears in the Unicode Hangul Jamo block, its usage in contemporary Korean is extremely rare, as it is not part of the standard 21 modern vowel combination set and is mostly encountered in linguistic transcription or historical orthography.
