Was it something like this?
>>> u'\xa0'.replace('\xa0', '')
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xa0 in position 0:
ordinal not in range(128)
You might get that if you're mixing str and unicode. If both strings are
of one type or the other, you should be okay:
>>> u'\xa0'.replace(u'\xa0', '')
u''
>>> '\xa0'.replace('\xa0', '')
''
