How about we turn the top bit on, giving us the next number as being 139
(128 + 11), considering the age of the engine, and the fact the current
value is 12, it's unlikely that Interbase will ever get to 128! By the
time we go from 139 to 255, the architecture will be so different, that
the numbers can simply roll over. Considering how unicode is going, a
char will soon become 4 bytes anyway.
