Escape and binary codes are entered via the well known ‘C’ style syntax
using the backslash character (‘\’). Inline spaces are treated as part
of the sequence.

\xhh ASCII character in hexadecimal notation
The sequence \xhh allows you to specify any ASCII character as a hexadecimal
character code. For example, you can give the ASCII backspace character
as the normal C escape sequence (\b), or you can code it as \x08 hexadecimal.
You must use at least one digit for a hexadecimal escape sequence, but
you can omit the second digit. Therefore, you can specify the hexadecimal
escape sequence for the backspace as either \x8 or \x08.
