To get started, you can look here . This should allow you to make Unicode printable for Eclipse on your console (which I don’t know if this is what Eclipse supports out of the box without any additional configuration)
If this does not solve your problem, you most likely have a problem with the encoding used by your program, so you may need to create lines in some way similar to this:
String str = new String("تعطي يونيكود رقما فريدا لكل حرف".getBytes(), "UTF-8");
That at least works for me.
