Re: eval() with unicode_literals?

Glad you like it. The trick is to ensure your source code is treated as 
Unicode by eval(). But even then, the only place your non-ascii 
characters can appear is inside a Unicode literal, signalled by the 
u-prefix (or maybe in comments). The following worked for me (in 2.7.1, 
under Eclipse):

import org.python.core.Py;
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;

public class UnicodeInterpret {
     public static void main(String[] args) {
         PythonInterpreter python = new PythonInterpreter();
         String source = "u'λαμβδα'";
         PyObject result = python.eval(Py.newUnicode(source));
         System.out.println(result);
     }
}
