Problem with accented characters

[carloscheddar]

Conflict between accented strings and ampersand(&) when query is parsed.

Error:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 27: ordinal not in range(128)

Details:
new_string = u'&'.join(parts[1:])

parts[1:] = ['properties.Municipio="Bayam\xc3\xb3n"', '_json_path=[0].geometry']

Make sure source-encoding is defined (see http://www.python.org/dev/peps/pep-0263/). Also, don't mix 'str' and 'unicode' types. Since a unicode ampersand u'&' is used to join the slice parts[1:], and the latter is a list of str, it breaks.
