Questions tagged [escaping]

Escaping is the process of applying an alternate meaning to a character or set of characters.

Escaping is used for many purposes, such as providing representations of unprintable characters, changing font colors in terminals, or allowing the inclusion in a string of a character normally used to terminate the string, as well as allowing to output a character to user when that character can be used as a control or markup character.

Some of the more common uses of escaping

  • URL encoding to allow including characters such as / or ?, and others, in URL queries;
  • XML and HTML entities that can be used to encode special characters that, for example, would normally be used for markup purposes.
