title: Unknown Encoding for Data Matrix encoded with google Barcode Scanner (Vision)
body: <p>I'm trying to scan some Data Matrix bar codes with my implementation of the Vision Barcode Scanner, but I'm having issues on the encoded ones.</p>
  
  <p>I'm using:</p>
  
  <pre><code>int codesDetected = Barcode.ALL_FORMATS;
  </code></pre>
  
  <p>But it still returns Unknown encoding for those ones.</p>
  
  <p>On the other hand, Google Goggles app scan them properly, same for some other bar code readers using zxing.</p>
  
  <p>Example of bar codes:</p>

  <p>I'm willing to move to Zxing if that solves the issue, but I want to know if there is something I'm missing in my implementation (I took the Vision sample app) for these type of bar codes (data matrix encoded).</p>
  
  <p>Thanks</p>
