mod_cloud_notify_encrypted: Ensure body substring remains valid UTF-8
The `body:sub()` call risks splitting the string in the middle of a
multi-byte UTF-8 sequence. This should have been caught by util.stanza
validation, but that would have caused some havoc, at the very least causing
the notification to not be sent.
There have been no reports of this happening. Likely because this module
isn't widely deployed among users with languages that use many longer UTF-8
sequences.
The util.encodings.utf8.valid() function is O(n) where only the last
sequence really needs to be checked, but it's in C and expected to be fast.

--- summary: Ad-hoc commands for managing MUC hats --- # Introduction This module provides an internal API (i.e. to other modules) to manage 'hats' for users in MUC rooms. Hats (first defined in [XEP-0317], currently deferred) are additional identifiers that can be attached to users in a group chat. For example in an educational context, you may have a 'Teacher' hat that allows students to identify their teachers. Hats consist of a machine-readable unique identifier (a URI), and optionally a human-readable label. This module provides ad-hoc commands for MUC service admins to add/remove hats to/from users in MUC rooms. It depends (automatically) on mod_muc_hats_api. ## Configuration ``` Component "conference.example.com" "muc" modules_enabled = { "muc_hats_adhoc" } ``` ## Usage To successfully use the module you will need to use an XMPP client that is capable of sending commands to a specific host (e.g. via the service discovery browser in Gajim, Psi/Psi+ and other clients), and you'll find the commands on the MUC host. Also note that the display of hats in clients is currently non-existent, but will hopefully improve after [XEP-0317] is resurrected or replaced.
