Yes, I tried only the fonts which have the cyrillic subset. I’m using the cyrillic subsets of such Google fonts as ‘PT Sans Narrow’ and ‘Cuprum’ on my other websites. I’m from Russia so the problem of cyrillic subsets is very actual for me 🙂 I already had this problem with some other themes, but this is the first time I can’t resolve it myself.
When I change this code to wp_enqueue_style("PT Sans Narrow", "http://fonts.googleapis.com/css?family=PT+Sans+Narrow:400,700&subset=latin,cyrillic", false, "1.0", "all");
and choose PT Sans Narrow in Custom Styles even latin subset stops working.
