mod_pubsub_summary: Use pre-escaped UTF-8 sequence for compat This silences a warning about using the non-existent global 'utf8' each time this line was hit. The utf8 library was introduced in Lua 5.3, so the warning would appear with 5.1 and 5.2.

summary: Presence deduplication module
labels:
- 'Stage-Alpha'
...

This module tries to squash incoming identical presence stanzas to save
some bandwidth at the cost of increased memory use.

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

  Option                         Type     Default
  ------------------------------ -------- ---------
  presence\_dedup\_cache\_size   number   `100`

The only setting controls how many presence stanzas *per session* are
kept in memory for comparing with incoming presenece.

Requires Prosody 0.10 or later.
