os.listdir() is broken with unicode characters in filenames, probably since one of the following revisions, which introduced 'throw new IllegalArgumentException("Cannot create PyString with non-byte value")' lines:
https://hg.python.org/jython/rev/f0c63b42e552
https://hg.python.org/jython/rev/521823de34a5

CPython 2.7 works correctly.

$ mkdir /tmp/some_dir
$ touch /tmp/some_dir/ś
$ python2.7 -c 'import os; print(os.listdir("/tmp/some_dir"))'
['\xc5\x9b']
$ jython2.7 -c 'import os; print(os.listdir("/tmp/some_dir"))'
