Running following code fails when using Jython 2.2.1 rc 1 but succeeds with Jython 2.2 (and earlier alphas/betas/rcs) and Python 2.3/2.4/2.5.

sys.stdout = StringIO()

print msg

assert sys.stdout.getvalue() == msg + '\n'

The traceback is below the code and shows that printing a unicode string fails even though in this case stdout has been intercepted.

Being able to print unicode strings like this is crucial in our case. We've been implementing a test automation framework that runs on Python and Jython and  it can be extended using so called test libraries which they can write messages to a common test log simply by writing to stdout. This way the API between the framework and libraries is pretty simple and it works the same way both when a lib is written in Python and when it's written in Java (we intercept java.lang.System.out too).
