These are actually two different things. One thing is how to deal with
hostnames with invalid UTF8 that are recieved from other hosts, and
the other is how to mangle the local hostname before publishing it on
the LAN. Ther former mapping requires perfect bijectiveness, the
It's perfectly valid for Apple to mangle the local host name the way
they do. However, I don't think it really is necessary. One could
publish an UTF8-Domain here directly. As long as it is correct UTF8 i
