Add the ability to handle non utf-8 characters

[amethystdragon]

In the format_results function in the CursorWrapper class in the file base.py the rows are run through an encoding process where they are encoded to utf-8.

I am using the FreeTDS driver with this library so self.driver_needs_utf8 is always True.

I have a problem where the MSSQL database I am interfacing with contains non-utf-8 characters. I have have only read access to the database and no control over the it to make changes that would resolve this.

In order to continue using the database I have two fixes.

One:
change ling 349 from: fr.append(row.decode('utf-8'))
to: fr.append(row.encode('ISO-8859-1').decode('utf-8'))

Two:
Override the init method in the CursorWrapper to automatically set driver_needs_utf8 to be False.

Would it be possible to incorporate a way in the options for the database to either encode from the database into what the database is encoded in and then decode it to utf-8 or setting the driver_needs_utf8 to be false in some way.
