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: summary: 'Module enabling "on-hold" functionality' ... Introduction ============ Enable mod\_onhold to allow temporarily placing messages from particular JIDs "on hold" -- i.e. store them, but do not deliver them until the hold status is taken away. Details ======= Right now, it is configured through adding JIDs to a list in prosody.cfg.lua. Eventually, more dynamically configurable support will be added (i.e. with ad-hoc commands or some such thing). Simply enable mod\_onhold in your list of modules, and then add a line: onhold\_jids = { "someone@address.com", "someoneelse@address2.com" } Until those JIDs are removed, messages from those JIDs will not be delivered. Once they are removed and prosody is restarted, they will be delivered the next time the user to which they are directed logs on.
