Punycoder converts international domain names to their (RFC1035 compatible) punycode representations on the commandline, so you can use them with nslookup or dig.

This is done by first converting the non-ASCII characters into their Unicode code points, and then encoding those code points using a special base-36 encoding scheme. The resulting string of ASCII characters is prefixed with the characters "xn--" to indicate that it is a Punycode-encoded domain name.
