It looks like there is some some problem on my side.
Opera browser where I am working - problem appears, Font is Lato.
Chrome - problem do not appear. But font is loading without proper codepage and polish diacritics are in different font than dejavu. Its weird, because ttf desktop font is with polish diacritics. Do I have to force somewhere loading of proper codepage?
opera, lato
chrome, dejavu, no polish diacritics
