text: # 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. 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.
  
  ## Character set
  
  Each character is given with a potential Unicode equivalent.
