They are very significant on systems where 'char' defaults to 'signed
char' (like ARM), and the characters are in the 128...255 range, since
then a negative offset will be taken, which is rarely what was
meant. This especially evil since often only 7 bit characters are in
use, so it goes unnotified for a while.
