Description

Related to bug 33048, I set my alias to 😼 (U+1F63C CAT FACE WITH WRY SMILE) and tried to join a MUC.

M-Link correctly rejects my request to join as follows:

_end_element_ns: Received stanza

• presence xmlns='jabber:client' type='error' to='will.thompson@collabora.co.uk/Queeg' from='foo@conference.jabber.org/😼'
  • status "XMPP Summit"
  • x xmlns='vcard-temp:x:update'
    • photo "57737ef652ef70b62edbfee5453e45bea6632b27"
  • x xmlns='http://jabber.org/protocol/muc'
  • error code='400' type='modify'
    • jid-malformed xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'

But we shouldn't ever get this far!

(This does raise the question of how we represent this restriction on romo nicknames. We arguably need this for IRC too.)
