I don't think that can be done. Regular expressions, which is what the matching here uses, don't have a concept of anything other than a character, that includes letters, numerals, punctuation and anything else. For example, the standard numerals set, \d, is to be interpreted as a set of characters representing (arabic) numerals, not as the numerals themselves.
