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.

A module providing a streaming statistics interface like [mod_statistics] but based on the new [statistics API][doc:statistics] introduced in Prosody 0.10. # Usage To use, enable the built-in statistics like so: ```lua statistics = "internal" ``` Then, in `modules_enabled`, replace `"statistics"` with `"statistics_statsman"` and the various `"statistics_<something>"` with equivalent `"measure_<something>"`. # Compatibility ------- -------------------- trunk Does not work [^1] 0.11 Should work 0.10 Should work ------- -------------------- [^1]: not after [5f15ab7c6ae5](https://hg.prosody.im/trunk/rev/5f15ab7c6ae5)
