I use PT Sans from Google Fonts. It has all the special chars I need (ą, ś, ź, ł etc). The problem is - Opera doesn't display them in bold (in CSS I write font: bold 16px/2em "PT Sans", sans-serif, so there is no way it could look for "PT Sans Bold" (but I did include PT Sans both 400 and 700). Firefox, Chrome and IE (8, 9) are doing fine.
What can I do?
