Is there a way to use Alt+numpad to write Unicode
characters in Emacs? Or does it need a patch?
Have someone tried it before?
If there are not a way to pass Alt+numpad keys to OS directly,
I could write a patch for w32. Is someone interested too? Some
suggestion to do this? (maybe a name for a global variable to
customize this behavior, like w32-ignore-alt-numpad, etc.)
Sorry if this mailing list is not the right place to ask this.

Why do you want to use Alt+numpad? You can already type an Unicode
codepoint with `ucs-insert' (bound to C-x 8 RET).

It's a long history, but basically because in all other programs
you can use Alt+numpad.

Thanks about that. I did not know about ucs-insert, but
still I need Alt+numpad behavior.
Another thing: I think it is impossible to emulate
the Alt+keypad just with elisp code because I need
to catch something like "Alt-unpressed" event.

If you mean that "the alt-numpad" feature works by recognizing the
"alt-unpressed" event as the sign that you've finished entering the
number, then indeed, it can't be done in Elisp right now and would
require changes to provide access to the up/down events for key presses
(I actually did code up such a change at some point in the past, to
play with it: it might be doable without introducing too many problems).

Like in GTK+ `Ctrl+Shift+U hex RET' http://en.wikipedia.org/wiki/Unicode_input
we could finish entering the number with RET, e.g. `M-2 M-7 M-0 M-f RET'.
Or expect a fixed-length four-digit number `M-2 M-7 M-0 M-f' where the last
fourth digit finishes the sequence. In any case, your up/down events code
would be useful for other purposes as well.
