$characters: This parameter specifies a character or sequence of characters which we want to escape in the input string and this can be achieved by adding the backslashes before them.
We can specify a range of characters as ‘a..j’ or ‘a..y’ etc. Before two dots, it is the start character of the range followed by two dots and the ending character can be written at the end of two dots.
