CGI::Untaint::printable(3) validate as a printable value


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


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.
