##IRI##
[Wikipedia 2016-03-05] Defined by the Internet Engineering Task Force (IETF) in 2005 as a new internet standard to extend upon the existing uniform resource identifier (URI) scheme. The new standard was published in RFC 3987. While URIs are limited to a subset of the ASCII character set, IRIs may contain characters from the Universal Character Set (Unicode/ISO 10646), including Chinese or Japanese kanji, Korean, Cyrillic characters, and so forth. It is defined by RFC 3987. IRI extend upon URIs by using the Universal Character Set whereas URIs were limited to the ASCII with far fewer characters. IRIs may be represented by a sequence of octets but by definition is defined as a sequence of characters because IRIs can be spoken or written by hand.
