It is saying any character in the set that is not a-z or 0-9.
NOTE: He's testing that a bad character is found (instead of that only good
characters are found) which should be slightly faster since it can return false
at the first bad character found. Make not of the ReFind**NOCASE** :) That
could trip you up if you used REFind.
