How can I specify the encoding of Java source files?

Question

I use weird Unicode strings in my Java test cases. The compiler seemingly interprets the file as iso-8859-1, causing JUnit to complain.

In Python I can specify the encoding at the top of the file:

# -*- coding: utf-8 -*-

Is there an equivalent in Java? How can I detect / specify the encoding of .java files?

It is compiler-dependent. You may also want to look at the [native2ascii](http://docs.oracle.com/javase/7/docs/technotes/tools/index.html#intl) tool to convert the code points to Unicode escape sequences. — McDowell, Feb 12 '12 at 12:55

You can set it when you compile the file with the parameter "-encoding"

The javac compiler has a parameter -encoding where you can set it. In Eclipse you must change the project settings or the global settings for *.java files.

The java compiler (javac) accepts an option -encoding. If you are using an IDE like Eclipse you can specify the encoding in the preferences.
