A literal newline may also be included in a string by preceding it with a backslash. Bytes may also be specified using an escape sequence $1, where $2 is the decimal value of the byte in the range 0–255. To include Unicode characters using escape sequences, the individual bytes for the UTF-8 encoding must be specified; in general, it will be more straightforward to enter the Unicode characters directly.
