Summarize this article for a 10 year old
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.
