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.

# Introduction This module lets you manage subscriptions to pubsub nodes via simple chat messages. Subscriptions are always added based on bare JID. The `include_body` flag is enabled so that a plain text body version of events can be included, where supported. # Configuring ``` {.lua} Component "pubsub.example.com" "pubsub" modules_enabled = { "pubsub_text_interface", } ``` # Commands The following commands are supported. Simply send a normal chat message to the PubSub component where this module is enabled. When subscribing or unsubscribing, be sure to replace `node` with the node you want to subscribe to or unsubscribe from. - `help` - a help message, listing these commands - `list` - list available nodes - `subscribe node` - subscribe to a node - `unsubscribe node` - unsubscribe from a node - `last node` - sends the last published item from the node to you # Compatibility Should work with Prosody since 0.9, when [mod\_pubsub][doc:modules:mod_pubsub] was introduced. The `last` command is available from Prosody 0.11.
