In regular expressions a backslash capital letter means the opposite. So, \D is NON-digits, \W is NON-word characters and \S is NON-whitespace. You can also do [A-z]* to get all letters in the English language plus the characters between them like ^ and literal \. I believe you can also do Unicode ranges with the respective \usomehex, but I haven't tried that yet.
