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.

prosody-modules =============== *Add-on modules for Prosody IM Server* -------------------------------------------------------------------------- Community repository for non-core, unofficial and/or experimental plugins for [Prosody][]. If you are a developer and would like to host your Prosody module in this repository, or want to contribute to existing modules, simply introduce yourself and request commit access on our [mailing list][]. Notes for users ---------------- There are lots of fun and exciting modules to be found here, we know you'll like it. However please note that each module is in a different state of development. Some are proof-of-concept, others are quite stable and ready for production use. Be sure to read the wiki page of any module before installing it on your server. We are working on methods to easily download and install modules from this repository. In the meantime most modules are either a single file and easy to install, or contain installation instructions on their wiki page. You can browse the files stored in this repository at <https://hg.prosody.im/prosody-modules>. [Prosody]: https://prosody.im/ [mailing list]: https://prosody.im/discuss
