Stanford Extended ASCII

Stanford Extended ASCII (SEASCII) is a derivation of the 7-bit ASCII character set developed at the Stanford Artificial Intelligence Laboratory (SAIL/SU-AI) in the early 1970s.^[1] Not all symbols match ASCII.

Carnegie Mellon University, the Massachusetts Institute of Technology, and the University of Southern California also had their own modified versions of ASCII.^[1]

Character set

Each character is given with a potential Unicode equivalent.
