the character code represented by the hexadecimal digits

\octal-digit…\           ISO

A backslash followed by a single newline character is ignored. The purpose of this is to allow a string or quoted-name to be spread over multiple lines.

\\, \', \", \`           ISO

Stand for the character following the ‘\’.
