Full Title or Meme

The American Standard Code for Information Interchange ASCII was created by Bell's Western Electric for teletypewriters.

Context

  • At the time this coding scheme was introduced the common teletypewriter code was Baudot, which was only 6 bits and required a shift key like that on the typewriter.
  • This was the default coding scheme at the start of the World Wide Web. It is still used in some coding situations where no ambiguity can be tolerated.

Problem

The standard does not comprehend many Western languages, let alone any Eastern languages.

Solutions

Most of the solutions create more problems than they solve.
