Punycode converter
Convert internationalized domain names (IDN): unicode to punycode (xn--) and back, both directions at once.
What is punycode?
Punycode is the ASCII notation of internationalized domain names (IDN). DNS only understands ASCII characters, so umlauts and other non-ASCII characters are encoded per RFC 3492 and marked with the xn-- prefix. Browsers and mail clients usually display the unicode form again.
Example: müller.de ↔ xn--mller-kva.de
