Discussion 🔗

A control character may be described as doing something when the user inputs them, such as a code 3 (End-of-Text character, ETX, ^C) to interrupt the running process, or a code 4 (End-of-Transmission character, EOT, ^D), used to end text input or to exit a Unix shell.

Some programming languages, like C, use NUL (U+0000) to mark the end of a string.

Examples include:

  • <Null> (NUL) (U+0000)
  • <Line Tabulation> (VT) (U+000B)
  • <Carriage Return> (CR) (U+000D)
