Introduction 1.1. Overview A number of technologies and applications provide the ability for a person to choose a memorable, human-friendly name in a communications context, or to set such a name for another entity such as a device, account, contact, or website. Such names are variously called "nicknames" (e.g., in chat room applications), "display names" (e.g., in Internet mail), or "petnames" (see [PETNAME-SYSTEMS]); for consistency, these are all called "nicknames" in this document. Nicknames are commonly supported in technologies for textual chat rooms, e.g., Internet Relay Chat [RFC2811] and multi-party chat technologies based on the Extensible Messaging and Presence Protocol (XMPP) [RFC6120] [XEP-0045], the Message Session Relay Protocol (MSRP) [RFC4975] [RFC7701], and Centralized Conferencing (XCON) [RFC5239] [XCON-SYSTEM]. Recent chat room technologies also allow internationalized nicknames because they support characters from outside the ASCII range [RFC20], typically by means of the Unicode character set [Unicode]. Although such nicknames tend to be used primarily for display purposes, they are sometimes used for programmatic purposes as well (e.g., kicking users or avoiding nickname conflicts).
