[eclipse] How to support UTF-8 encoding in Eclipse

How can I add UTF-8 support in eclipse? I want to add for example Russian language but eclipse won't support it. What should I do? Please guide me.

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 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.

See https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/envvars002.html

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

Try this

• 1) Window > Preferences > General > Content Types, set UTF-8 as the default encoding for all content types.

• 2) Window > Preferences > General > Workspace, set Text file encoding to Other : UTF-8

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 insall command.

You may require to install Language Packs: 3.2

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.
