Wonseok (원석; Stone, Ore) is a Korean Input Method Editor (IME) for Minecraft GuiTextFields.
Since LWJGL 2 disables IMEs on non-Windows systems, I wrote this mod to input Korean.
Currently, the only layout supported is dubeolsik (2벌식). The system is extensible, however, so 3벌 support should be fairly easy to implement.
Also planned is a 'Romaja' input, which 'hangeulizes' input into Korean, for instance, 'annyeong' would become '안녕'.
