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.

| 8 # Introduction | |
| 9 | |
| 10 This module provides a streaming interface to [Prosodys internal statistics][doc:statistics] via | |
| 11 [Server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events). | |
| 12 | |
| 13 ## Example | |
| 14 | |
| 15 ```js | |
| 16 var evtSource = new EventSource("/stats_stream"); | |
| 17 | |
| 18 /* | |
| 19 * An event with all current statistics in the form of a JSON object. | |
| 20 * Normally sent only once, when first connected to the stream. | |
| 21 */ | |
| 22 evtSource.addEventListener("stats-full", function(e) { | |
| 23 var initial_stats = JSON.parse(e.data); | |
| 24 console.log(initial_stats); | |
| 25 }, false); | |
| 26 | |
| 27 /* | |
| 28 * An event containing only statistics that have changed since the last | |
| 29 * 'stats-full' or 'stats-updated' event. | |
| 30 */ | |
| 31 evtSource.addEventListener("stats-updated", function(e) { | |
| 32 var updated_stats = JSON.parse(e.data); | |
| 33 console.log(updated_stats); | |
| 34 }, false); | |
| 35 ``` | |
