How to bind “ß” to Meta-s?

Question

I am using Carbon-Emacs on MacOS X 10.6 with the US-International keyboard layout. Usually, I can use Alt+s to print the letter "ß". However, Emacs interprets this as Meta+s and complains that there is no command bound to that shortcut. So my questions are:

1. How can I create such a shortcut?
2. Is there another way to print the character "ß"?

Answer 1

Answer to 1.

Try adding this to your emacs configuration file (should be ~/.emacs.d/init.el or alike):

(define-key global-map [(meta s)] [?\u00DF])

Answer 2

Put the following in your .emacs ... I don't use a Mac, so I couldn't test that side of it. However this works for me.
The original define-key global-map presented by Björn Pollex did not work for me, but his latest version using (U+00DF) does work (for me), I can't tell from your comments (till now), if it works for you.. If it doesn't, try this one..

(defun insert-sharp-s ()
  "Insert Unicode Character 'LATIN SMALL LETTER SHARP S' (U+00DF)"
       (interactive)
       (insert "ß")
       )
(global-set-key "\M-s" 'insert-sharp-s)
