FAQ
Are double finals supported?+
ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅄ — all decompose and recompose correctly.
Why is jamo decomposition useful?+
(1) Initial-consonant search ('ㅎㄱ' → '한국'), (2) IME conversion, (3) Korean phonology algorithms. Essential for Korean apps and search.
Same as Unicode jamo?+
Uses Unicode Hangul Jamo (U+1100~U+11FF), not the compatibility jamo (U+3131~U+318F).
What about combined vowels (ㅘ, ㅝ)?+
By default they're one unit. An option further decomposes them to ㅗ+ㅏ.
Example: initial-consonant search?+
Decompose each character → extract initials → match user input. '한국' → 'ㅎㄱ', '한식' → 'ㅎㅅ'.
Performance concerns?+
Each character takes microseconds. Tens of thousands of characters process instantly.
