Trigraphs are three-character sequences used to enter single conceptual characters that cannot be entered from the computer keyboard for various reasons: obsolete keyboard, input of special characters is required, the text editor reserves some characters for special use, etc. Trigraphs can also be used to extend the keyboard.

Different systems have different sets of defined Trigraphs.
