Summary: make_table in difflib does not work with unicode

Initial Comment:
make_table function in difflib.HtmlDiff does not work correctly when input strings are unicode.
This is because the library uses cStringIO.StringIO classes, and cStringIO.StringIO returns strings encoded by the default encoding.
When the default encoding is 'ascii', for example, this behaviour becomes a problem because some unicode characters cannot be encoded in 'ascii'.
 
So, please change cStringIO to StringIO in difflib.py.
When I use StringIO in difflib.py, this function returns unicode strings and no problems occured.
 
This problem occured in Python 2.5/2.4 on Windows XP.
