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> <p>[<a href="rsyslog_conf.html">rsyslog.conf overview</a>] [<a href="manual.html">manual index</a>] [<a href="http://www.rsyslog.com/">rsyslog site</a>]</p> <p><font size="2">This documentation is part of the <a href="http://www.rsyslog.com/">rsyslog</a> project.<br> Copyright © 2007 by <a href="http://www.gerhards.net/rainer">Rainer Gerhards</a> and <a href="http://www.adiscon.com/">Adiscon</a>.
