title: UnicodeDecodeError Loading with sqlalchemy
body: <p>I am querying a MySQL database with sqlalchemy and getting the following error:</p>
  
  <pre><code>UnicodeDecodeError: 'utf8' codec can't decode bytes in position 498-499: unexpected end of data
  </code></pre>
  
  <p>A column in the table was defined as <code>Unicode(500)</code> so this error suggests to me that there is an entry that was truncated because it was longer than 500 characters. Is there a way to handle this error and still load the entry? Is there a way to find the errant entry and delete it other than trying to load every entry one by one (or in batches) until I get the error?</p>
