incorrect console output in different projects at same machine

I've spent almost 3 days to find out why in a big project the output of

System.out.println( "你好" );

is shown as "??" and in another project built-from-scratch it is shown as "你好".

I am using IntellijIdea, BUT the same thing happens to me while running it from a jar-file using

java -jar ...

The only two differences between those 2 project is in build system: first one uses gradle and second one uses none (just a simple project). The second difference is about output of the following code

     System.out.println("Charset.defaultCharset=" + 
     Charset.defaultCharset());

The first one types "Charset.defaultCharset=windows-1252", second one "Charset.defaultCharset=UTF-8"

Well, I HAVE read about:

1. the encoding in IntellijIdea, all settings between 2 projects are the same (Settings → File Encoding → Project Encoding → IDE Encoding)

2. About the encoding of file setting in the right lower corner in Idea

3. Tried -Dfile.encoding=UTF-8 and then -Dconsole.encoding=UTF-8 in debug configurations for all gradle instances

4. in cmd console did

   set JAVA_TOOL_OPTIONS=-Dconsole.encoding=UTF8
   
   set JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF8
   

5. Played with gradle properties in gradle.build

   org.gradle.jvmargs='-Dfile.encoding=UTF-8'
   systemProp.file.encoding=UTF-8
   

6. changed the the coding in command prompt via

   chcp  65001
   

Those efforts bring me to nothing. Any ideas ?

BTW THERE IS almost the same question but with no answer. I cannot write there cause of low reputation Intellij Idea incorrect encoding in console output

the picture with settings in project that don't correctly display the output

Well, finally i've got it!

Navigate to Help -> Edit Custom VM Options...

Add those ones:

-Dfile.encoding=UTF-8
-Dconsole.encoding=UTF-8

Restart idea completely.
