Because of an issue in the way multi-byte rule names are handled, you must ensure that the instance of Red Hat CodeReady Studio is started with the file encoding set to UTF-8. You can do this by editing the $DS_HOME/studio/codereadystudio.ini file and adding the following property: "-Dfile.encoding=UTF-8".
