When in Korean IME mode,
pressing spacebar once results two spaces instead of one.
Reproduced below,
First line is in Korean IME, pressing a<space><space>b<space><space>c<space><space>
Second line is doing the same strokes but in English IME mode.

I've checked with the same font on different app(Mac's Terminal Emulator), and it doen't happen there.
