<h2>$EscapeControlCharactersOnReceive</h2>
<p><b>Type:</b> global configuration directive</p>
<p><b>Default:</b> on</p>
<p><b>Description:</b></p>
<p>This directive instructs rsyslogd to replace control characters during reception of the message. The intent is to provide a way to stop non-printable messages from entering the syslog system as whole. If this option is turned on, all control-characters are converted to a 3-digit octal number and be prefixed with the $ControlCharacterEscapePrefix character (being '\' by default). For example, if the BEL character (ctrl-g) is included in the message, it would be converted to "\007". To be compatible to sysklogd, this option must be turned on.</p>
<p><b>Warning:</b></p>
<ul>
<li>turning on this option most probably destroys non-western character sets
(like Japanese, Chinese and Korean)</li>
<li>turning on this option destroys digital signatures if such exists inside
the message</li>
<li>if turned on, the drop-cc, space-cc and escape-cc
<a href="property_replacer.html">property replacer</a> options do not work
as expected because control characters are already removed upon message
reception. If you intend to use these property replacer options, you must
turn off $EscapeControlCharactersOnReceive.</li>
</ul>
<p><b>Sample:</b></p>
<p><code><b>$EscapeControlCharactersOnReceive on</b></code></p>
