CGI::Untaint::printable(3p)

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.
