[Jython-users] Umlaut encoding issue in UncaughtExceptionHandler (windows)

[Niemann, H. <har...@si...>]

Hello!

I am using Jython 2.7.0 embedded into a java application, that is: not the jython.exe, on windows.

When an exception parameter or a line in the stack trace contains an Umlaut, there seems to be an exception in the exception handler itself, 
because all I get (if one of the source lines has umlauts) is

	Exception in thread "main"
	Exception: org.python.core.PyException thrown from the UncaughtExceptionHandler in thread "main"

If the string representation of the exception itself contains an umlaut, stack trace and type of the exception are printed, but the argument is missing.

(If run from jython.exe, the output is completely readable, although some garbage characters are printed instead of the umlauts, which is (sort of) to be expected.)

if I catch the exception  like
		except Exception as e:
			print ('Uncaught exception in main: %s' % e)
			print (sys.exc_info())
			import traceback
			traceback.print_tb(sys.exc_info()[2])
i get reasonable output.

---- the snippet from the embedding java function is:
		//start python
		PythonInterpreter.initialize(null, null, argv.toArray(new String[0]));

		PythonInterpreter py;
		py = new PythonInterpreter();

		//exec
		py.exec("import cpsgen_py");

		PyObject ret;
		ret = py.eval("cpsgen_py.main()");

		if (ret instanceof PyInteger) {
			return ((PyInteger) ret).getValue();
		}
--- a simple examle to try is
	s = 'Hallöle'
	assert False, s  # ä

What do I see here? Am I doing something wrong when setting up the interpreter?
