python - Tkinter international bind

Question

Is there a way in Tkinter to bind a combination of keys that will work in all keyboard layouts? (bind by scancode)

For example, I need 'Control-Z' binding that will work with the same physical key in the lower left corner of the keyboard in all layouts, such as:
    * Russian layout,
    * Greek layout, etc.

Here's what I tried:

from Tkinter import *
root=Tk()
def f(event):
    print 'undo'
button1=Button(root, text=u'Button')
button1.pack()
button1.bind('<Control-z>', f)
root.mainloop()

It doesn't work for Russian and Greek keyboard layouts.

Update-2:

I did some more experiments with Windows and now the general rule is like that:

    1) If the language is based on latin character set, keys are mapped "by value" (German, French, Dvorak) so that the same action is mapped to different physical keys.
    2) If it is not (eg Russian, Greek), then all major accelerators are mapped "by position" (to match the corresponding English letter usually marked on the same key).

Only the second case needs special attention. Any ideas if this is implemented in some lib already?

Update-3

It is simply reproduced even without Russian keyboard or Russian Windows.

1) Start->Control Panel->Regional and Language Options
2) Language->Details
3) Add Russian language.

That's it. Now Alt-Shift will switch you to Russian and you'll be able to type the following funny symbols:

another Alt-Shift will switch you back.

Forget what Wikipedia says about phonetic Russian layouts. They are not used these days. At least inside Russia.

All Windows applications (including wxPython ones) use Ctrl-я for undo, Ctrl-ч for cut, Ctrl-с for copy and so on.

Answer 1

What I'm primarily interested in is Russian layout in Windows.

The quick and dirty workaround I currently use is:

import Tkinter

def copy(event):
    print 'Ctrl-C'

root = Tkinter.Tk()
root.bind('<Control-ntilde>', copy)
root.mainloop()

which could potentially lead to a conflict with <Ctrl + actual ntilde> in some other language.

It could be overcome if I could determine which layout is currently active, thus second question: Tkinter determine keyboard layout.

Another drawback is that due to 'universal' treatment of modifier keys it also fires when I press Ctrl-Alt-V, but that's another story as it applies to English layout as well.
