in reply to Regex - Char Class Question

I don't think it is so much the tilde(~)being at the end but the hyphen (-) not being on one of the ends. That is, if the hyphen is not at either end of the character class then it becomes a range for whatever two chars it is in between.This should work the same as all the others for instance:
$a =~ /^[-\w.~]+$/

    See perlop. If you're going to put a ] or - character into your character class then it has to be either escaped or be placed at the front after the optional ^,

      See perlop.

      Actually, see perlre.

      If you're going to put a ] or - character into your character class then it has to be either escaped or be placed at the front after the optional ^,

      Or placed at the end immediately before the closing square bracket.

      The relevant passage from perlre: 

           If you want either "-" or "]" itself to be a member of a
     class, put it at the start of the list (possibly after a
     "^"), or escape it with a backslash.  "-" is also taken
     literally when it is at the end of the list, just before the
     closing "]".
