1.  Introduction

1.1.  Overview

   Technologies for textual chatrooms customarily enable participants to
   specify a nickname for use in the room; e.g., this is true of
   Internet Relay Chat [RFC2811] as well as multi-party chat
   technologies based on the Extensible Messaging and Presence Protocol
   (XMPP) [RFC6120] [XEP-0045], the Message Session Relay Protocol
   (MSRP) [RFC4975] [I-D.ietf-simple-chat], and Centralized Conferencing
   (XCON) [RFC5239] [I-D.boulton-xcon-session-chat].  Recent chatroom
   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).  Note too that nicknames can be used
   not only in chatrooms but also more generally as a user's preferred
   display name (see for instance [XEP-0172]).

   Nicknames (also called "petnames") are also used in contexts other
   than messaging, such as petnames for devices, bank accounts, and the
   like.  The rules specified in this document can also be applied to
   such nicknames.
