Keyboard emulation special chars on non standard locale

Did you want a BELGIAN keyboard layout or a DUTCH keyboard layout?

Windows has three different Belgian keyboards. On this one:

The '@' is AltGr-2. You can't put that in _asciimap because the ASCII map has no way to specify an AltGr shift. I would try:

  Keyboard.press(KEY_RIGHT_ALT);
  Keyboard.press('2');
  Keyboard.releaseAll();
