Comment 4 for bug 1629894

>Files uses hardware keycodes to identify keyboard events for 'C', 'V' and 'X' so Ctrl-C, Ctrl-V and Ctrl-X should work with different keymaps (assuming the modifier keys work normally).

Unfortunately bug works as well not only for text, but also for files in opened folder. Right now I can't copy single file (named on english) from usb flash to hard drive, but if I close Files and reopens it - bug will be disabled for some time.
