Everyone should keep in mind that when C was created in the early 70's,
ASCII and EBCDIC were the only games in town. Even when the second
edition of this book was written in 1995, assuming ASCII was perfectly
acceptable in the English speaking world, which at the time did most of
the computing.

When I learned Pascal at Santa Monica City College in 1983, teachers
took special care to teach us ord() and chr(), and a lot of our lab
exercises converted back and forth.
