Encoding of body_params vs param/params

[patrickbkr]

• Dancer2 v0.200001

• config.yml has charset: "UTF-8" set.

• When doing

  my @params = (Empfänger => '毛泽东');
  $user_agent->post(
      $url,
      'Content-type' => "application/x-www-form-urlencoded; charset='utf8'",
      Content      => [ map { Encode::encode_utf8( $_ ) } @params ],
  );
  

• params returns

  { Empfänger => '毛泽东' }
  

• and body_parameters returns

  { Empfänger => '�泽�' }
  

• When doing a map { Encode::decode( "utf-8", $_) } on that I get the decoded version.

I tracked params down to Request.pm:312: $self->_params which is initialized in line 460 with $self->_body_params wich does a _decode in line 125.

And body_parameters in Request.pm:368: return $self->env->{'plack.request.body'}.

I am rather unskilled with providing good information. So if I should provide more (which?) information, please say so!

Looking at code and tests (t/dsl/parameters.t) this actually looks intentional though I have not (yet) found anything in the docs that mentions this difference.

@PerlDancer (especially @xsawyerx) I've been hunting through the various issues and PR #988 but I can't find any discussion or explanation for this particular difference between params and parameters. Can anyone help enlighten us?

@PatZim many thanks for spending the time to submit this detailed issue. I've created PR #1219 which addresses it.
