    Description

      The registry has a restriction "DNS-valid names only" to retain the future option of DNS exporting of the registry.

      to handle complex usernames, it punycodes the username first, using Java's java.net.IDN class.

      This turns out to only map high unicode-> ASCII, and does nothing for ascii-but-invalid-hostname chars, so stopping users with DNS-illegal names (e.g. with an underscore in them) from being able to register
