U+11EF "ᇯ" Hangul Jongseong Ieung-Khieukh Unicode Character

U+11EF "ᇯ" Hangul Jongseong Ieung-Khieukh is a composite consonant used in the Korean Hangul writing system, specifically as a final consonant or batchim (jongseong) in a syllable block. It represents a combined sound formed by the letters ieung (ㅇ) and khieukh (ㅋ), which together produce a velar nasal followed by an aspirated velar stop, similar to the "ng-k" sound found in the English word "ink". This character is part of the Hangul Jamo Extended-A block in Unicode and is historically or phonetically necessary for accurate representation of certain Korean syllables, though it is not commonly used in modern standard Korean orthography.
