title: convert byte array to string without interpreting the bytes?
body: <p>I have a GSM date/time stamp from a PDU encoded SMS it is formatted as so</p>
  
  <p>\x90,\x21,\x51,\x91,\x40,\x33</p>
  
  <p>format yy,mm,dd,hh,mm,ss</p>
  
  <p>I have read them from a binary file into a byte array. I want to convert them to a string but without doing any decoding I want to end up with a string that contains 902151914033. I then need to reverse each 2 characters in the string.</p>
  
  <p>Can anyone give me some pointers?
  Many Thanks </p>
