First you need to define what you mean by binary and text.
Is a file "text" simply because it contains only the
printable (in ASCII) bytes between 31 and 127, plus 
CR and/or LF, or do you have a more complex definition 
in mind.

Better yet, what do you need the information for?  Maybe
the answer to that will show us the proper path to take.
