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: Replace LaTeX markup in messages with embedded images
...

Introduction
============

This module intercepts messages between users and into chatrooms, and
attaches a links to a rendered version of any
[LaTeX](http://en.wikipedia.org/wiki/LaTeX) in the message. This
requires client support for
[XHTML-IM](http://xmpp.org/extensions/xep-0071.html), and fetching
images via HTTP.

This module was tested with the [Gajim](http://gajim.org/) client.

Details
=======

There is no configuration (yet). The module uses
[MathTran](http://www.mathtran.org/) to render the LaTeX.

Todo
====

-   Support for other rendering services (easy)
-   Provide a built-in rendering service (e.g. mimetex)
-   Send the images inline over XMPP (little client support at the
    moment)

Compatibility
