I’m not so convinced. Until now, I had no problem with that font in the other templates. It was enough to add “latin-ext” and on all devices and browsers Polish characters display them properly. After adding “<link href=’http://fonts.googleapis.com/css?family=PT+Sans+Narrow&subset=latin,latin-ext’ rel=’stylesheet’ type=’text/css’>” to the header.php problem go away, but that’s not the point.
