Alt+numpad to write special symbols

[David Capello]

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.
