title: Rails 3 Encoding::CompatibilityError
body: <p>I am working on a rails app that submits a french translation via ajax and for some reason I keep getting the following error in the log:</p>
  
  <p><code>Encoding::CompatibilityError incompatible character encodings: UTF-8 and ASCII-8BIT</code></p>
  
  <p>Does anyone know how to fix this?</p>
  
  <p>FIX:This works on the WEBrick sever</p>
  
  <p>Place <code># encode: UTF-8</code> at the top of each file you want to work with different chars</p>
  
  <p>I can't get this to work on a rails server with Thin... anyone else run into this?</p>
