I recommend that you work with Unicode wherever possible. If pymssql
can't handle Unicode then use UTF-8 when talking to it. The result
should look something like this:

>>> con = pymssql.connect(host='testdb',user='testuser',password='password',database='test')
>>> sql = u"insert into table_1 values ('£')".encode("utf-8")
>>> cur.execute(sql)
>>> con.commit()
>>> sql = u"insert into table_1 values ('1')".encode("utf-8")
>>> cur.execute(sql)
>>> con.commit()
>>> sql = u"select * from table_1".encode("utf-8")
>>> cur.execute(sql)
>>> result = cur.fetchall()
>>> result
[('\xc2\xa3',), ('1',)]

You'll then need to decode from UTF-8:

>>> [tuple(field.decode("utf-8") for field in row) for row in result]
[(u'\xa3',), (u'1',)]
>>> print u'\xa3'
£
