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.

--- summary: 'Receives HTTP POST request, parses it and relays it into XMPP.' --- Introduction ============ Sometimes it's useful to have different interfaces to access XMPP. This module allows sending XMPP [`<message>`](https://xmpp.org/rfcs/rfc6121.html#message) stanzas via a simple HTTP API. Example usage ------------- curl http://example.com:5280/msg/user -u me@example.com:mypassword -H "Content-Type: text/plain" -d "Server@host has just crashed!" This would send a message to user\@example.com from me\@example.com Details ======= URL format ---------- /msg/ [recipient [@host] ]. The base URL defaults to `/msg`. This can be configured via Prosodys [HTTP path settings][doc:http]. Authentication -------------- Authentication is done by HTTP Basic. Authentication: Basic BASE64( "username@virtualhost:password" ) Payload formats --------------- Supported formats are: `text/plain` : The HTTP body is used as plain text message payload, in the `<body>` element. `application/x-www-form-urlencoded` : Allows more fields to be specified. `application/json` : Similar to form data. Which one is selected via the `Content-Type` HTTP header. ### Data fields The form data and JSON formats allow the following fields: `to` : Can be used instead of having the receiver in the URL. `type` : [Message type.](https://xmpp.org/rfcs/rfc6121.html#message-syntax-type) `body` : Plain text message payload which goes in the `<body>` element. Acknowledgements ================ Some code originally borrowed from mod\_webpresence See also ======== [mod_rest] is a more advanced way to send messages and more via HTTP, with a very similar API.
