title: Encoding::UndefinedConversionError: "\xC2" from ASCII-8BIT to UTF-8
body: <p>I received the following error upon saving a new contact. Is there a way to cast <code>"\xC2"</code> so that it can be forced to be saved in the UTF-8 format? </p>
  
  <pre><code>c = Contact.new
  c.save!
  </code></pre>
