It was asked at Stackoverflow. There some trolls marked my posting negative. It is actually a real engineering problem being faced right now. Can you guys help me with it? http://stackoverflow.com/questions/33631652/converting-to-jython-a-python-3-5-project-coding-error Best Regards, Daniel

The severity was changed to critical because many people are utilizing already the latest Python modules and interpreter. And they might want to add Java functionality to their code. So they would basically have to backport it to Python 2.7 then to Jython 2.7 subsequentely.

The code in the SO post: FS_ENCODING = 'ascii'; fn = b('[abc\xff]'); encoded = u('[abc\udcff]') appears to be testing/expecting that the invalid ascii character '\xff' will be encoded into the invalid unicode string '\udcff'. This is used in CPython to byte-smuggle non-ascii file names through unicode strings. Jython approaches differently. Versions after 2.7.0 may be able to treat this code more gently. A much fuller consideration is given in #2340, #2342. Maybe allow one/both of these to supersede this ticket?
