            Note: Because MUC roomnicks follow the Resourceprep profile of stringprep, they are allowed to contain a space character, whereas IRC nicknames do not. Although a given client MAY support quotation characters for this purpose (resulting in commands such as '/ban "king lear" insanity is no defense'), most common quotation characters (such as " and ') are also allowed by Resourceprep, thus leading to added complexity and potential problems with quotation of roomnicks that contain both spaces and quotation characters. Therefore it is NOT RECOMMENDED for XMPP clients to support IRC-style shortcut commands with roomnicks that contain space characters.
