The OCR may well say "0" where the printing says "8" but what your eyes 
will see will be the representation of the printing. So if you rely only 
on OCR you may well miss something, but if you fall back to the way 
you'd have towork without OCR (or even the way you'd have to work if you 
had the original paper copy) then you have to rely on your eyesight to 
fail to find what you are looking for ...

Unless, that is, you discard the graphical representation and keep only 
the OCR result. In which case all bets are off.
