Korean does not store its letters separately. A syllable such as 한 is a single code point built from three letters, and Unicode fixes the arithmetic: code = 0xAC00 + (initial × 21 + medial) × 28 + final.
Splitting matters when you build initial-consonant search — the feature that lets someone type ㄱㅁ and find 김밥. The index is built from the initials, so you need the syllables taken apart first.
It also matters for counting. A text field limited by letters rather than syllables, or a sort that has to match a legacy system, both need the parts rather than the character.
The deep option breaks compound letters further: ㅘ becomes ㅗ plus ㅏ and ㄺ becomes ㄹ plus ㄱ. Keyboard work needs that; initial-consonant search does not, so both are offered.
Putting letters back together is the harder direction. When a letter could be a final consonant but is followed by a vowel, it belongs to the next syllable instead. That single decision is what separates 간 from 가나.
