Current Behavior

Monkeytype only expects NFC-encoded (precomposed) Hangul (Korean writing system), and if NFD-encoded (decomposed) Hangul is entered, it is marked as incorrect.

Expected Behavior

NFD-encoded Hangul should be normalized before comparison.

Steps To Reproduce

1. Use an input method which inserts decomposed Hangul Jamo
2. Monkeytype will mark everything entered as incorrect

Confirming the issue is not with input itself, as everything renders correctly in zen mode.
