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 Many projects have a support room accessible via a web chat. This module allows making the URL to such a web chat discoverable via the XMPP service discovery protocol, enabling e.g. [search engines](https://search.jabbercat.org/) to index and present these. # Configuring ## Enabling ``` {.lua} Component "rooms.example.net" "muc" modules_enabled = { "muc_webchat_url"; } ``` ## Settings The URL is configured using the in-band MUC room configuration protocol. The module can optionally be configured to give all public (not members-only, hidden or password protected) rooms gain a default value based on a template: ``` {.lua} muc_webchat_baseurl = "https://chat.example.com/join?room={node}" ``` The following variables will be subsituted with room address details: `{jid}` : The complete room address, eg `room@muc.example.com`· `{node}` : The local part (before the `@`) of the room JID. `{host}` : The domain name part of the room JID.
