Submit

Language is selected by the extension of the file. See the list of supported languages to know the extension of your language.

Problem

Punycode is an ASCII representation of UTF-8 words. It is used in international domain names. Build a simple encoder. The RFC 3492 contains an example C implementation.

This is a Chaos Codegolf Challenge: If you are attending the 27th Chaos Community Congress, you can win some bottles of Mate ;). Just enter "27c3" as the beginning of your name and come to get your price on day 2 (28th) and 4 (30th). See the wiki for more information: http://v.gd/27c3golf

Please note: To participate in the challenge, you are not allowed to use punycode libraries, e.g. Python's encode('punycode')
