  coded character set
  
     <character, standard> A mapping from a set of integers to a
     set of characters.  This mapping is generally 1:1 (i.e.,
     bijective), for example, the code position 65 in ASCII
     maps only to "A", and it's the only position that maps to "A".
  
     There are several standard coded character sets, the most
     widely used is ASCII, generally in its Latin-1 dialect,
     with Unicode becoming slowly more common; while EBCDIC and
     Baudot are extinct except in legacy systems.
  
     A coded character set may include letters, digits,
     punctuation, control codes, various mathematical and
     typographic symbols, and other characters.  Each character in
     the set is represented by a unique character code (or "code position
     ").
