Short description of error
Hello. I am Korean. Thank you for developing the blender. I'm using the latest version of blender. But there's one serious problem.
It is not possible to switch from "English Input to Korean Input" in TEXT mode.
This is also true of Chinese and Japanese keyboards.
We would appreciate it if you could correct the "Switching language input" bug in TEXT mode.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
