Encoding issues when parsing source code

I'm still running into encoding issues when parsing the source. Simply open the setup.py of programslice in vim and slice it. You get:

Error detected while processing function <SNR>36_slice_buffer:
line   14:
Traceback (most recent call last):
  File "<string>", line 10, in <module>
  File "/opt/works/vim/ftplugin/python/programslice/__init__.py", line 76, in slice_string
    node = ast.parse(source.decode(encoding), name)
  File "/usr/lib/python2.7/encodings/utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf3' in position 263: ordinal not in range(128)
