Punycodenoun
A mapping from Unicode to the simpler ASCII character set, intended for the representation of international domain names where Unicode is not available.
Wikipedia
Punycode
Punycode is a representation of Unicode with the limited ASCII character subset used for Internet hostnames. Using Punycode, host names containing Unicode characters are transcoded to a subset of ASCII consisting of letters, digits, and hyphens, which is called the letter–digit–hyphen (LDH) subset. For example, München (German name for Munich) is encoded as Mnchen-3ya. While the Domain Name System (DNS) technically supports arbitrary sequences of octets in domain name labels, the DNS standards recommend the use of the LDH subset of ASCII conventionally used for host names, and require that string comparisons between DNS domain names should be case-insensitive. The Punycode syntax is a method of encoding strings containing Unicode characters, such as internationalized domain names (IDNA), into the LDH subset of ASCII favored by DNS. It is specified in IETF Request for Comments 3492.

Punycode
In computing, Punycode is an instance of a general encoding syntax by which a string of Unicode characters is transformed uniquely and reversibly into a smaller, restricted character set. Punycode is intended for the encoding of labels in the Internationalized Domain Names in Applications framework, such that these domain names may be represented in the ASCII character set allowed in the Domain Name System of the Internet. The encoding syntax is defined in IETF document RFC 3492. The IDNA methodology encodes only select label components of domain names with a procedure called ToASCII. The procedure ToUnicode decodes the DNS label into Unicode representation.
