The writing system of Korean, Hangul, is an alphabet organized into blocks of syllables; characters cannot just be written from left to right. Because of this, every possible syllable in Korean must either be rendered as syllable blocks by a font, or be encoded separately. Unicode uses the latter option. As an example, the syllable 하 (ha) consists of the characters ㅎ (h) and ㅏ (a), but all of them are encoded separately.
