Just a question about strange characters ( ) in syslog file

[pemca]

Hi, and thanks for at great library.

I use it with rsyslog server on debian and wonder why i get strange characters ( ) in syslog file.

Aug 11 18:00:57 esp32-1 RC-Switch Temperature Sensor 1 26.000000

It is OK if i change this in syslog.cpp
if (this->_protocol == SYSLOG_PROTO_IETF) {
//this->_client->print(F(" - - - \xEF\xBB\xBF"));
this->_client->print(F(" - - - "));
} else {
this->_client->print(F("[0]: "));
}

I know this is not OK, but could you explain ?

thanks,

Hello pemca,

Sorry for late answer, it's BOM (Unicode Byte Order Mark) to support UTF-8 characters in a message as is described here: https://tools.ietf.org/html/rfc5424#section-6

Anyway there is open issue rsyslog/rsyslog#284, but it should be fixed since rsyslog v1.0.1.
