Type: global configuration parameter
This parameter 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.
- turning on this option most probably destroys non-western character sets (like Japanese, Chinese and Korean)
- turning on this option destroys digital signatures if such exists inside the message
- if turned on, the drop-cc, space-cc and escape-cc property replacer 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.
