Punycode is a standard method for encoding Unicode characters into ASCII for use in domain names. It is designed to support domain names that contain characters that are not part of the basic ASCII set.

However, with the expansion of the Internet and various language characters such as Cyrillic, Chinese and Japanese characters, it became necessary to provide the ability to include these characters in domain names.

Punycode represents non-ASCII Unicode characters as france email list a sequence of ASCII characters called an ACE (ASCII-Compatible Encoding) encoding. An ACE encoding consists of a " xn—" prefix followed by an ASCII sequence representing the Unicode characters. For example, the character "á" is encoded as " xn--9caa" in Punycode.

When a domain name contains characters that are not supported by standard ASCII, Punycode allows these characters to be represented as an ASCII-compatible sequence that can be used in domain names. This allows for the use of different languages ​​and characters in domain names, making the Internet more accessible and usable for users of different languages ​​and cultures.
