Unfortunately, with the rise of UNICODE, \d is no longer what one
expects* ([0-9]). It now includes all characters marked as digits in
UNICODE. This includes characters like "\x{1813}" (MONGOLIAN DIGIT
THREE). The \w character class also no longer matches [a-zA-Z0-9_],
but instead matches any character marked as a word character by
UNICODE; however, this is much less of a problem since, unlike digits,
a character is still a character (try adding "\x{1813}" + 1).
* note, you can get the old behavior back by using the bytes pragma.
