Intellij Idea incorrect encoding in console output

问题:

It seems to be really crazy, but I can't do anything with broken encoding in console of my intellij idea.

Things I made to overcome this:

1. Set -Dfile.encoding=UTF-8 and -Dfile.encoding=UTF-8 in both idea.exe.vmoptions and idea64.exe.vmoptions (I use 64 bit version though).
2. Added -Dfile.encoding=UTF-8 and -Dfile.encoding=UTF-8 to run/debug configuration of my application.
3. Changed Settings > Editor > File encodings IDE Encoding/Project Encoding/Default encoding for property files to UTF-8.

Having all this done there is still no luck and symbols are not shown correctly in the console. I tried to debug java.io.PrintStream#println(java.lang.String) method and found out that System.out.textOut.out.se.cs equals to windows-1251. No idea where this value is coming from.

This issue have been bothering me for a long period of time and I was unable to find anything in the web that could help me.

Thanks in advance for help.

try

-Dconsole.encoding=UTF-8

instead of

-Dfile.encoding=UTF-8

My theory is that your java class file are using "windows-1251" encoding, and you need to set it "UTF-8".

looks at the screenshots below.

To reset all files encoding, you can manually edit encodings.xml. You can change the default file encoding in settings dialog.

In my case examining System.out.textOut.out.se.cs in debug hinted that IDEA picked up maven surefire arguments for every JUnit Run Configuration:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <!-- force 7-bit default encoding to ensure that nothing depends on it -->
        <argLine>-Dfile.encoding=ASCII</argLine>
    </configuration>
</plugin>

I've resolved this by adding -Didea.maven.surefire.disable.argLine=true to idea64.exe.vmoptions file.
