- mix of language sets from 'preferred' language not allowed.
- Language sets from CLDR dataset.

Rejecting

@ -50,9 +53,13 @@ Rejecting
on creation and on events.
- Any home server whose domain does not pass this check, MUST use their punycode
domain name instead of the IDN, to prevent other home servers rejecting you.
- Error code is M_FAILED_HOMOGRAPH_CHECK.
- Error code is ``M_FAILED_HUMAN_ID_CHECK``. (generic enough for both failing
due to homograph attacks, and failing due to including ``:``s, etc)
- Error message MAY go into further information about which characters were
rejected and why.
- Error message SHOULD contain a ``failed_keys`` key which contains an array
of strings which represent the keys which failed the check e.g:
- ``failed_keys: [ user_id, room_alias ]``
