You are right in that indeed I was a bit hasty: Convertin LATIN-1 to  
UTF-8 is easy, but vice versa is not, at least not if you want to  
cover all cases correctly. So, we could implement a limited back  
conversion that only handles most cases, but not all. *However*, that  
wouldn't be very nice at all.

So, either LATIN-1 or we stay with ASCII. I wonder if any other porter  
has to say anything? Else, I'll just make the required changes when I  
find the time.

Bye,
