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.

--- labels: - 'Stage-alpha' summary: Save received chat markers into MUC archives' ... Introduction ============ Chat markers (XEP-0333) specification states that markers _SHOULD_ be archived. This is already happening in one to one conversations in the personal archives but not in Group Chats. This module hooks the _muc-message-is-historic_ event to customize the `mod_muc_mam` behavior and have the chat markers archived. Usage ===== First copy the module to the prosody plugins directory. Then add "muc\_mam\_markers" to your `modules\_enabled` list in your MUC component's definition. No configuration options are available.
