U+AF78 "꽸" Hangul Syllable Ggwaess Unicode Character
U+AF78 "꽸" Hangul Syllable Ggwaess is a precomposed syllable in the modern Korean writing system, formed by combining the initial consonant "ㄲ" (a tense, double "g" sound), the vowel "ㅙ" (a diphthong pronounced like "wae"), and the final consonant "ㅆ" (a tense, double "s" sound). This specific syllable, which represents a sound that does not commonly appear in standard modern Korean vocabulary, is part of the Hangul Syllables block (AC00 D7A3) and was encoded in Unicode as part of the initial 1993 version 1.1 release. It is used primarily as a phonetic building block in Korean text, ensuring that all logically possible combinations of jamo (letters) are digitally representable, even if the syllable itself is rare or often found only in transcribed foreign words or marginal contexts.
