New issue 3091: update description_encoding for pyodbc

Mike Bayer:

it seems like our defaults on this are out of date, examine pyodbc behavior re: cursor.description and see if we can either change the default, or put in a detection for it, possibly for 1.0 since this may be destabilizing:


```
#!python

#! coding: utf-8

from sqlalchemy import *

engine = create_engine("mssql+pyodbc://scott:tiger@ms_2008", echo=True,
                        description_encoding='utf8')

colname = u'Заказ.Номер заказа'

m = MetaData()
t = Table(u"Заказы", m, Column(colname, String(30), key='somecol'))

m.drop_all(engine)
m.create_all(engine)

engine.execute(t.insert().values(somecol='some value'))
result = engine.execute(t.select().where(t.c.somecol == 'some value'))
row = result.fetchone()
print row[t.c.somecol]


```
