Delete character

The delete control character (also called DEL or rubout) is the last character in the ASCII repertoire, with the code 127.^[1] It is supposed to do nothing and was designed to erase incorrect characters on paper tape. It is denoted as ^? in caret notation and is U+007F in Unicode.

Terminal emulators may produce DEL when ← Backspace key or Control+← Backspace or Control+? are typed.
