Internationalized Resource Identifier

Expanded set of characters on the URI protocol

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. 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, IRIs may additionally contain most characters from the Universal Character Set, including Chinese, Japanese, Korean, and Cyrillic characters.
