title: Invalid binary character when transmitting ProtoBuf-net messages over AWS SQS
body: <p>I'm using Protobuf-net (<a href="https://code.google.com/p/protobuf-net/" rel="noreferrer">https://code.google.com/p/protobuf-net/</a>) to serialize my class, and then trying to transmit this via amazon SQS.</p>
  
  <p>When I do that I get this error:</p>
  
  <pre><code>Amazon.SQS.AmazonSQSException: Invalid binary character '#xC' was found in the message body, the set of allowed characters is #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF].
  </code></pre>
  
  <p>which is pretty self-explanatory.</p>
  
  <p>Has anyone got a good solution on how to get this working?</p>
