IntelliJ IDEA incorrect encoding in console output

Question

It seems to be really crazy, but I can't do anything with broken encoding in the 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 these done, there is still no luck and symbols are not shown correctly in the console. I tried to debug the 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 has been bothering me for a long time and I was unable to find anything in the web that could help me.

Solution 1

This works for me.

1. Close your intellij idea
2. 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
3. (Optional) if you have file idea64.exe.vmoptions, add the same line too.
4. Start your intellij idea.

Solution 2

try

-Dconsole.encoding=UTF-8

instead of

-Dfile.encoding=UTF-8

Solution 3

You may have modified the wrong file，

not : C:\Program Files\JetBrains\IntelliJ IDEA xxxx\bin\idea64.exe.vmoptions

should be: C:\Users\USER_NAME\.IntelliJIdeaxxxx\config\idea64.exe.vmoptions

you can add both -Dfile.encoding=UTF-8 and -Dconsole.encoding=UTF-8

Solution 4

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.
