title: kafka-console-consumer.sh suspected as performing decoding
body: <p>I'm using the kafka-console-consumer.sh OOB script from kafka installation folder.
  While trying this script with on a byte input, in which is an Hex code values, I'm having the results as the original values.</p>
  
  <p>i.e.
  input: 68656c6c6f20776f726c64
  script output is: hello world</p>
  
  <p>I suspect that this OOB script decode hex values.
  Anyone can approve/deny that ?</p>
  
  <p>Thanks !</p>
