Well, I see some strange stuff in the input processing.

Please add this snippet:

  DebPrint (("key_event: %d %d 0x%x 0x%x {0x%x 0x%x} 0x%x\n",
             event->bKeyDown, event->wRepeatCount,
             event->wVirtualKeyCode, event->wVirtualScanCode,
             event->uChar.AsciiChar, event->uChar.UnicodeChar,
             event->dwControlKeyState));

at the very beginning of key_event function (in w32inevt.c), attach
GDB to a running "emacs -Q -nw", and tell me what does GDB report when
you type non-ASCII keys on your keyboard.

That is,

  emacs -Q -nw
  gdb -p EMACS-PID
  (gdb) continue

then type non-ASCII characters into Emacs.  You should see messages
such as these:

  warning: key_event: 0 1 0x54 0x14 {0xffffff80 0x580} 0x20

  warning: key_event: 1 1 0x54 0x14 {0xffffff80 0x580} 0x20

(but with different codes).  There are 2 messages for each keystroke:
one when the key is pressed, the other when it is released.  Please
post here the exact output, and please tell for each pair of such
messages which character did you type.
