   You are aware that a string IS a char array, right?
   
   byte charVal = (byte)("Hello, World!")[0];

   Although this works for some strings, note that it only works with strings made from 7bit ASCII characters (0-127).
   
   I'm looking for a "better" solution that just allows me to look at the byte encoding of the string without go through text encoding transformations.
