GIMP 2.10.2 Windows x86 Only, Keyboards Key Binding Error

GIMP version: GIMP 2.10 2

Operating System: MS Windows 10 version 1803 x86 Only!

Package: Official Installer from gimp.org (gimp-2.10.2-setup.exe) + change DLLs (#1516 (closed))

Description of the bug

I do not know whether it is environment dependent or locale dependent,
On Windows x86 only, keyboard binding is out of order.
In the Japanese environment, if you type the ascii character, the correct one will not call back.
I think that it is probably a trouble with GLib. I am not familiar with this, so I do not know the details ...

Currently, I am taking measures by starting Japanese IME and entering characters.
Originally, this is unnecessary for ascii input, but I can type letters correctly.
It is impossible for keyboard shortcut by this solution, so now, I open the history or I use menu items.

PS; Not only me, Another Japanese user reported me that a same situation is occurring (on my blog's comments).
He(/She?) is taking measures by adding the US keyboard driver.
Yes. Of course, it is not necessary to add such a driver, usually.

Is the bug reproducible? Always
