do you want to use translated eclipse or simply change the file encoding? – Barbary

Is this about code, or resources? UTF-8 resource support takes a bit more work. – Buss

I wrote a blog post about this very topic which illustrates this in great detail (with screenshots etc): Unicode/UTF-8 in your Eclipse Java projects – Ow

I am not able to accept UTF-8 characters as input from console. Scanner sc=new Scanner(System.in); sc.nextLine(); here if I give non-English characters it gets something garbage. What changes needed in setting or in program ? – Finsteraarhorn

Kaushik Lele: Your question does not relate the the question asked here. I invite you to search for your solution in other questions, or if none exist, ask your own question. – Geulincx

That is pretty awful... surely the encoding of a project should be dependent on the project, not on the global Eclipse settings? – Buss

@Nyerguds: In the Package Explorer, right-click on a project and choose Properties'. The first entry Resource' offers exactly what you want. – Xanthus

Open Eclipse and do the following steps:

1. Window -> Preferences -> Expand General and click Workspace, text file encoding (near bottom) has an encoding chooser.
2. Select "Other" radio button -> Select UTF-8 from the drop down
3. Click Apply and OK button OR click simply OK button

You can set a default encoding-set whenever you run eclipse.exe.

1. Open eclipse.ini in your eclipse home directory Or STS.ini in case of STS(Spring Tool Suite)
2. put the line below at the end of the file

-Dfile.encoding=UTF-8

@Farkhod Abdukodirov I think file encoding is not an UTF-8 when to set up your eclipse project so it might be a problem though... – Durware

Just right click the Project -- Properties and select Resource on the left side menu.

You can now change the Text-file encoding to whatever you wish.

it worked for me , thanks. In fact, until I reach this answer comment, I tried all, but unfortunately they didn't work, maybe it also depends on OS system environment. – Drily

Answer 6

September 24, 2022 Update:
JDK 19 (released on September 20, 2022) has System property

stdout.encoding

which can be set to UTF-8, i.e. add the following option to the java command:

-Dstdout.encoding=UTF-8

If you have Windows 11, and none of the previous answers worked, you could need to change your Region settings. Follow these steps:

Quick instructions:

Windows search > Control Panel > Region > Administrative tab > Change system locale... > check Beta: Use Unicode UTF-8 for worldwide language support > OK > Restart now

Full instructions:

1. Go to the Windows search: Press the Win key, or just click on the Search button. Another way you can go is by pressing the Win + s shortcut.
2. Type Control Panel and press enter key to open it, or simply click on the first search result.
3. Click on the View by dropdown menu in the upper right corner and select Category (if the view is not set by Category).
4. Go to Clock and Region.
5. Click on Region.
6. Go to the Administrative tab.
7. In Language for non-Unicode programs, click on Change system locale... button.
8. Check the Beta: Use Unicode UTF-8 for worldwide language support option.
9. Click OK.
10. Click Restart now.

You should be able to see the characters properly in Eclipse.

I tried all settings mentioned in this post to build my project successfully however that didn't work for me. At last I was able to build my project successfully with mvn -DargLine=-Dfile.encoding=UTF-8 clean install command.

Answer 9

You can set an explicit Java default character encoding operating system-wide by setting the environment variable JAVA_TOOL_OPTIONS with the value -Dfile.encoding="UTF-8". Next time you start Eclipse, it should adhere to UTF-8 as the default character set.

If you have problems with JSON files, it turns out in some Eclipse versions there is an embedded JSON Validator. You can turn it off by doing the steps below:

Go to Windows->Validation and Uncheck JSON validation checkboxes
