I've configured NXlog to send printing events from our Windows 2012R2 print server to our Nagios LS instance. **Except **for the following issue, it works well.

The issue is - when a filename contains a "%" sign, I receive a _grokparsefailure in Nagios. That led me to NXLog-CE and how it (and its modules) read/parsed the data from the Microsoft Windows PrintService Event Log. I enabled troubleshooting by means of debug AND outputting the $raw_event to a text file.

Is there a way I can get this document name from the Windows Event Viewer into Nagios via NXlog-CE? This issue looks similar to this thread, which says the problem is with the provider: https://nxlog.co/question/2362/problem-windows-event
