I don't wish to seem like I'm advocating stupidity, but keep in mind
that not every machine represents its character set in 7 bits, nor
can one implement "tolower" and "toupper" just by xor'ing a bit --
not every machine uses ASCII.  

Portability and "standards" sometimes have interesting wrinkles to them.
