title: tiny_tds error on heroku connecting to SqlServer db
body: <p>I'm using the tiny_tds and activerecord-sqlserver-adapter gems to connect to a remote sqlserver database.  I have it working locally but when I deploy to heroku I get the following error.</p>
  
  <p><strong>ActiveRecord::StatementInvalid: TinyTds::Error: Unicode data in a Unicode-only collation or ntext data cannot be sent to clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier.</strong></p>
  
  <p>Is there setup needed on heroku to get this working?</p>
