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 exposes ad-hoc commands [XEP-0050] for listing uploaded files, and
later for managing them.

Configuration
=============

This module depends on mod\_http\_upload, and exposes ad-hoc commands for each
operation a user might do on their uploaded files.

The module can be added to the `modules_enabled` field on a host on which
mod\_http\_upload is loaded.

Compatibility
=============

Works with Prosody trunk at least.
