This works for me.
- Close your intellij idea
- Search and open file idea.exe.vmoptions inside idea installed, for example: “C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.2\bin”.
After add next line: -Dfile.encoding=UTF-8 - (Optional) if you have file idea64.exe.vmoptions, add the same line too.
- Start your intellij idea.
