The docs for [:digit:] and [:xdigit:] seem clear enough, but there is one other minor point that could be clarified. The [:alnum:] and [:alpha:] are based on (unspecified values of) the Unicode general-category property, but [:digit:] is not. Thus [:alnum:] includes other numeric characters that are not matched by [:digit:]. AndyM
