Re: CGI::Application - Which is the proper way of handling and outputting utf8

OK, now I have modified my application to start with:

use utf8; # to state that the script itself is in utf8
binmode STDIN, ":encoding(utf8)";
binmode STDOUT, ":encoding(utf8)";
use as_utf8; # which is the hack posted at http://www.perlmonks.org/?node_id=651574

in setup():
$self->header_add(-charset => 'utf-8');

Any final comments/thougts?

With the 'as_utf8' hack, you do not need `binmode STDIN, ":encoding(utf8)";`. In fact, it will cause problems if you have a binary/file upload field in a web form, since it will try to UTF-8 decode the incoming binary file/data. The as_utf8 hack correctly only decodes text form field data. Instead of `binmode STDOUT, ":encoding(utf8)";`, you can put the following in cgiapp_postrun(): `sub cgiapp_postrun { # overrides my ($self, $output_ref) = @_; utf8::encode( $$output_ref ) if utf8::is_utf8($$output_ref) }` [download] This will only UTF-8 encode the output if it needs encoding -- i.e., only if it $output_ref contains non-ASCII characters.

binmode STDIN, ":encoding(utf8)";

Instead of binmode STDOUT, ":encoding(utf8)";, you can put the following in cgiapp_postrun():

sub cgiapp_postrun {  # overrides
  my ($self, $output_ref) = @_;
  utf8::encode( $$output_ref ) if utf8::is_utf8($$output_ref)
}
