in reply to leaving only [a-zA-Z0-9]

you can also use $a =~ s/\W//g;

If you use locales; it supports special chars too.

    make that   s/[\W_]//g;   to take away the   _   too.

    And careful with   locale!   That will not get rid of Umlauts and word characters with accents and such. It will still get rid of special characters though.

      "That will not get rid of Umlauts and word characters with accents and such." - that are the specialchars I've meant.
      Sorry I should have been more detailed in my explanation.
