How do I correctly display "Check domain" results and responses from the Port 43 Whois?

All registered .INFO IDNs are available both in the Port 43 and Web-based Whois, just as regular .INFO registrations are today. Both the Port 43 and Web-based Whois will display the Punycode string that has been actually registered as the domain name and an HTML representation of the Unicode equivalent. Registrars wishing to display the Unicode/UTF-8 equivalent for the domain name in question can do so by integrating the output from the “Unicode HTML” field into their Whois applications.
