Internationalized Resource Identifier
Expanded set of characters on the URI protocol / From Wikipedia, the free encyclopedia
The Internationalized Resource Identifier (IRI) is an internet protocol standard which builds on the Uniform Resource Identifier (URI) protocol by greatly expanding the set of permitted characters.[1][2][3] It was defined by the Internet Engineering Task Force (IETF) in 2005 in RFC 3987. While URIs are limited to a subset of the US-ASCII character set (characters outside that set must be mapped to octets according to some unspecified character encoding, then percent-encoded), IRIs may additionally contain most characters from the Universal Character Set (Unicode/ISO 10646),[4][5] including Chinese, Japanese, Korean, and Cyrillic characters.
