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.

| 3844 | 6 This module provides **public** access to Prosodys |
| 7 [internal statistics][doc:statistics] trough the | |
| 8 [XEP-0039: Statistics Gathering] protocol. This is a simple protocol | |
| 9 that returns triplets of name, unit and value for each know statistic | |
| 10 collected by Prosody. The names used are the internal names assigned by | |
| 11 modules or statsmanager, names from the registry are **not** used. | |
| 12 | |
| 13 # Configuration | |
| 14 | |
| 15 Enabled as usual by adding to [`modules_enabled`][doc:modules_enabled]: | |
| 16 | |
| 17 ```lua | |
| 18 -- Enable Prosodys internal statistics gathering | |
| 19 statistics = "internal" | |
| 20 | |
| 21 -- and enable the module | |
| 22 modules_enabled = { | |
| 23 -- other modules | |
| 24 "stats39"; | |
| 25 } | |
| 26 ``` | |
| 27 | |
| 28 # Usage | |
| 29 | |
| 30 | |
| 31 ## Example | |
| 32 | |
| 33 Statistics can be queried from the XML console of clients that have one: | |
| 34 | |
| 35 ```xml | |
| 36 C: | |
| 37 <iq type="get" to="example.com" id="dTMERjt5"> | |
| 38 <query xmlns="http://jabber.org/protocol/stats"/> | |
| 39 </iq> | |
| 40 | |
| 41 S: | |
| 42 <iq type="result" to="example.com" id="dTMERjt5"> | |
| 43 <query xmlns="http://jabber.org/protocol/stats"> | |
