Katalon Studio decode .xlsx and .log files.

Hello, everyone. Please help to solve issue with encoding files in Katalon Studio. I’ve installed the latest version of studio - Katalon_Studio_Windows_64-7.9.1 on Windows 10
osgi.arch=x86_64 and all .xlsx, .log, .sqlite so on files are decoded. Text file encoding set as default to UTF-8 in workspace->settings. .ini file also has property -Dfile.encoding=utf-8 Do you have an idea how to handle that?
