Korean ↔ English Typing Converter

Korean ↔ English Typing Converter: Fix text typed with the wrong keyboard layout. If you accidentally typed Korean characters when you meant to type English (e.g., 'ㅗ디ㅣㅐ' → 'hello'), use Korean→English. For the reverse (e.g., 'gksrmf' → '한글'), use English→Korean. Auto-detect identifies the input language automatically.
