U+11A9 "ᆩ" Hangul Jongseong Ssangkiyeok Unicode Character

U+11A9 "ᆩ" Hangul Jongseong Ssangkiyeok is a jamo used in the Korean writing system as a final consonant (받침) representing the doubled "ㄱ" sound, which is pronounced as a tense, unreleased velar stop [k̚] at the end of a syllable. This character is part of the Hangul Compatibility Jamo block and serves to indicate the final consonant cluster historically transcribed as "ㄲ" in syllable-final position. While its visual form resembles two stacked "ㄱ" shapes, it is a single typographic unit. In modern Korean, the use of ᆩ is less common than its initial or medial counterparts, but it remains essential for accurately encoding certain words and maintaining orthographic consistency in texts such as historical documents or specific academic transcriptions.
