Right. That's because the space key does not return any other character
then 0x20 in the Windows console, regardless of the modifier keys you're
pressing. Same goes for Alt-Space which should ideally return Esc-Space
or \240. Maybe we should really add that while we're at it.
From my emacs-centric view of things, I think you should. Both
Alt-Space and Control-Space are used a lot in emacs, especially
Control-Space.
2. Control-Alt-<any key> does not appear to generate anything (or maybe
it generates NUL).
That's a longstanding problem which probably can't be fixed satisfingly.
On non-English keyboards, the right Alt key is called AltGr and returns
the modifiers Left-Control/Right-Alt. It's used to enter certain
characters which are not accessible using the normla keys with just the
shift modifier. For instance, on a german keyboard, the keys [/{ and
]/} are replaced with Umlaut-u and +/* keys. To enter the square and
curly braces, one has to type AltGr-7 up to AltGr-0. The problem is,
you can't distinguish between pressing Ctrl+Alt and pressing AltGr on
these keyboards (or rather, in these keyboard settings).
What do linux and xterm do? Ctrl+Alt is a commonly-used key combination
in emacs, so it would be surprising if they didn't work on a non-English
keyboard. But I've never had occasion to try it, and I don't have
access to a non-English keyboard right now. Maybe Andy knows the
answer. In mintty, can you distinguish between Ctrl+Alt and AltGr on a
non-English keyboard?
