I was expecting the client to provide the domain in punycode form. :)

Restricting to what is used by the underlying dns seemed logical, 
although my
main interest was doing in the server the cleanup so that it doesn't end 
up with
control characters, .., backticks, slashes et al. so that for instance 
the following
naive script would be safe:

set -e
tar -c .
