I'm getting data corruption when a UTF-8 encoded web page sends form data back to Dancer via POST. As far as I can tell, the browser is doing the right thing and submitting the data as UTF-8 -- verified with Firebug -- but when I try to retrieve the data with param(), Dancer treats it as something else. To see this, say "dancer -a utf8form" and edit two of the files: 1. Replace the contents of utf8form/views/index.tt with: <form method="post" action="/submit"> <input name="field" type="text"/> </form> 2. Add a POST handler route to utf8form/lib/utf8form.pm: post '/submit' => sub { debug "Got '", param('field'), "' from form."; }; Since my terminal uses UTF-8 and default Dancer apps have UTF-8 in config.yml and the generated HTML templates, the debug() call shouldn't need any special help, IMO. Try submitting "Español", for example.
