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-Beta' summary: 'Log/archive all user messages' ... Introduction ============ Often service administrators need to log their users' messages for reasons such as auditing and compliance. This module simply logs user messages to simple text files, which can be easily searched, archived or removed on a regular basis. Usage ===== Simply load the module and it will start logging.

Configuration ============= Option name Description ----------------------- ----------------------------------------------------------------------------------------------------------------------- message\_logging\_dir The directory to save message logs in.
