Indeed, Swiss German keyboards do not have '�' (which was a real pain 
when doing a German language course on Windows which insisted I used it).

That's a useful document.  The last paragraph on Page 10 might mean you 
need to clean up existing data:

"NEW: Due to the new regulation of German spelling the letter � is after 
a short (stressed) vowel now replaced by ss. The letter � remains after 
a long vowel or a diphthong."

Yes I would expect problems with web based forms. On OS X I can get � 
via option-s, but on Windows that is alt-0223, not something I expect a 
typical end user to remember.

I had an example the other day in a Captcha which decided from my IP 
address that I needed German when viewing a UK based website.  I wish 
that if they are going to do that they would get it right...
