How to register and purchase an IDN?
An Internationalized Domain Name (IDN) is a domain name that may contain characters outside the ASCII character set.
The IDN system allows Internet users to use the full alphabet of their language in their domain names. They’re no longer restricted to the English A-Z, and can use the full latin character set, as well as characters from other locales, including Chinese and Japanese.
IDN Domains work by encoding the domain name using a system called Punycode (see RFC 3492).
