If player uses other IME(CJK IME probably non-english IME), Player can't control game.
I thinks this problem is caused by minecraft control setting is detect alphabet only.
Please fix this problem.
It is not serious problem, but It is bad for game experience(even worse in multiplayer)
Sorry for bad english 😞
Environment
Windows 10, 64-bit
last version of Java 8
Uses Korean IME(I tried other IME like Japanese, also not working too)
Confirmed. Same error here.
