!!! Overview
[{$pagename}] ([IRI]) was defined by the [Internet Engineering Task Force] ([IETF]) in [2005|Year 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 [Uniform Resource Identifiers] are limited to a subset of the [ASCII] character set, [Uniform Resource Identifiers] may contain characters from the [Universal Coded Character Set] ([Unicode]/[ISO 10646]), including Chinese or Japanese kanji, Korean, Cyrillic characters, and so forth.

!! [{$pagename}] and [Security Considerations]
Mixing [{$pagename}]s and [ASCII] ] can make it much easier to do [phishing] [attacks] that trick someone into believing they are on a site they really are not on. For [example], one can replace the "a" in www.ebay.com or www.paypal.com with an internationalized look-alike "a" character such as <α>, and point that [IRI] to a [malicious] site. This is known as an [IDN homograph attack].
