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.
