I wasn't very clear on this, sorry.
"Check my å" is not inside the code, it comes from my "po/mo"-files (i18n).

It looks actually more like this:

 $c->redirect(
  $c->uri_for(
    '/login',
    {error_msg => $c->loc("Check my magic")}
  );
 );

po-file (utf8 encoded):
 msgid "Check my magic"
 msgstr "Check my å"
