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.

# Introduction

This module writes out a traceback to a file when a chosen signal (by default
`SIGUSR1`) is received. It can be useful to diagnose cases where Prosody is
unresponsive.

# Configuration

`debug_traceback_filename`
:   The name of the file to write the traceback to. Some variables
    are supported, see [mod_log_ringbuffer] docs for more info. Defaults
    to `{paths.data}/traceback-{pid}-{count}.log`.

`debug_traceback_signal`
:   The name of the signal to listen for. Defaults to `SIGUSR1`.

# Compatibility

Prosody 0.11 or later.
