Escape sequence - Wikipedia

Escape sequence

In computing, an escape sequence is a sequence of characters that has a special semantic meaning based on an established convention that specifies an escape character prefix in addition to the syntax of the rest of the text of a sequence.12 A convention can define any particular character code as a sequence prefix. Some conventions use a normal, printable character such as backslash () or ampersand (&). Others use a non-printable (a.k.a. control) character such as ASCII escape.

Escape sequences date back at least to the 1874 Baudot code.345
