NAME

       CGI::Untaint::printable - validate as a printable value

SYNOPSIS

         my $name = $handler->extract(-as_printable => 'name');

DESCRIPTION

       This Input Handler verifies that it is dealing with an 'printable' string i.e. characters
       in the range \040-\377 (plus \r and \n).

       The empty string is taken to be printable.

       This is occasionally a useful 'fallback' pattern, but in general you will want to write
       your own patterns to be stricter.
