Fix a regression in the .de and .dk whois special cases

Ensure the special cases trigger whether we come via a referral
or via the -c option. Match host names case-insensitively.

Use the default character set supported by .de (UTF-8) since that
is more compatible with the modern world than ISO 8859-1. Persuade
them to give us a useful answer whether an internationalized
domain name is given in UTF-8 or in punycode.
