An internationalized domain name (IDN) is a domain name that is available to an Internet user in a non-ASCII character set. A user types a URL in his/her local language, and it is converted into an equivalent string of characters in the ASCII character set.
- ↑ For an example of characters and how they are converted into a non Latin-alphabet language, see IANA, .JP Japanese Character Table. Relevant RFCs for IDNs are: RFC 3490, RFC 3491, and RFC 3492. See Internet FAQ Archives, Internet RFC/STD/FYI/BCP Archives. See also resources collected at ICANN, Internationalized Domain Names.
