Why? What about and faç What about and What about and This is a matter of  
spelling. Historically ß has been uppercased as SS and SZ and ẞ.  
Only one of those is reversible.

It seems to me that it is time (also for .de and .at) to bite the  
bullet and accept that in IDN ss and ß are just as different as th and  
þ are.
