Since we know this : $string =~ s/([a-fA-F0-9][a-fA-F0-9])/pack ("C", hex($1))/eg;
is a statement which can converting back the "real string" from
a form field, but, could anybody tell how to convert the "real string"
to the "long long" string ??
Besides, anybody can tell what is the exactly meaning of : ("C", hex($1)) ?
