1. 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 code points from
outside the ASCII range [RFC20], typically by means of the Unicode
coded character set [Unicode]. Although such nicknames tend to be
