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.

7 In anonymous and semi-anonymous rooms, the mentioned user needs to have their nickname registered in the MUC so that Prosody can get the real JID from the referenced nickname. |

9 NOTE: this module is not compatible with mod_block_strangers because the latter will block the notification messages from the MUC (since they're not "groupchat" messages). |
