Hangul Jamo is a Unicode block containing positional (choseong, jungseong, and jongseong) forms of Hangul consonant and vowel clusters (). While the Hangul Syllables Unicode block contains precomposed syllables used in standard modern Korean, the Hangul Jamo block can be used to compose arbitrary syllables dynamically, including those not included in the Hangul Syllables block.
In Unicode normalization forms C and KC (NFC and NFKC), the character sequence [ᄀ-ᄒ][ᅡ-ᅵ][ᆨ-ᇂ]? (one character from U+1100 to U+1112, and then one character from U+1161 to U+1175, and then optionally one character from U+11A8 to U+11C2) is converted to a single character in the Hangul Syllables Unicode block (e.g. ᄉ+ᅫ+ᆵ (U+1109, U+116B, U+11B5) → 쇒 (U+C1D2)).
