Fix a regression introduced in test_sys by r83778.

setup_context() replaces .pyc or .pyo filename suffix by .py, but it
didn't work if the filename contains a non-ascii character because the
function used the wrong unit for the length (number of characters
instead of the number of bytes).

With this patch, it uses unicode filenames instead of bytes filenames,
to fix the bug and to be fully unicode compliant.

shutdown.

Use ``encoding="unicode"`` to generate a Unicode string.
