The code 127 ( DEL) is also a control character. All other characters are mainly printing, printable, or graphic characters, except perhaps for the " space" character (see ASCII printable characters).Īll entries in the ASCII table below code 32 (technically the C0 control code set) are of this kind, including CR and LF used to separate lines of text.

They are used as in-band signaling to cause effects other than the addition of a symbol to the text.
