This is indicated by including a '^' as the first character of the class; '^' outside a character class will simply match the '^' character. For example, [^5] will match any character except '5'. " ^ does not simply match ^ outside a character class since is a special character that represents the start of the string. I think the paragraph should read: You can match the characters not listed within the class by complementing the set. This is indicated by including a '^' as the first character of the class; '^' will act differently outside a character class as explained later. For example, [^5] will match any character except '5'.
