      Description

      Running a Java spring boot web application using a "java -jar" type of command with a pretty vanilla log4j2.xml file in it, I see the following error.

      I am running the "run" command on Windows 10 64x inside a ConEmu console. If I switch to Babun, then I don't see the error.

      This may not exactly be a "bug", but it would be great to not crash the app and fallback to a more accepting encoding perhaps.
