   The American Standard Code for Information Interchange [...] is a
   character-encoding scheme [...] <URL:

   Unicode is a computing industry standard for the consistent encoding,
   representation and handling of text [...] <URL:

Each standard assigns numbers to letters and other symbols. In a word,
each is a code. That's what their names say, too.
