Partially - it depends on OS used. In DOS we are limited to 256
characters. In Windows we can use all those characters that a particular
font supports. For example, Alt+0149 != Alt+149 - try it yourself and
you'll feel the difference.

Yes, you're quite right but please don't forget the Alt hold down. It
changes the way the OS interprets the scan codes of these keys - it
means: store the NumPad input in a special buffer and simulate
entering a character according to the decimal ANSI code received.

Again, please remember that we're holding Alt down.

I suggest trying to enter � character (Alt+0149) in the Start - Run
window which is a part of Windows unlike all the applications discussed
here. You'll always get the correct input regardless of the NumPad
status.
