   Another way to do it, which I have seen used in the Paracel   
   FDF/TextFinder hardware search processor is to supply a bit mask for   
   each character being compared.  Only bits with a '1' in the mask are   
   used in the comparison.  (Bitwise AND with the mask, and compare to   
   the previously masked query character.)
