Source Sans Pro font lacks cyrillic support

Hi.

Sorry for the late replay, I did not see this new issue.

Source Sans Pro does not support Cyrillic, unfortunately :-(. And we did not provide a way to deactivate it from the UI.

The solution would be to create a very simple subtheme. Add your own CSS file to it (ex: `css/font.csss`) and put the following rule inside:

body {
  font-family: Helvetica, Arial, sans-serif;
}

That will do the trick. If you need help on how to create a subtheme, just let me know.

Add to "CSS overrides" section of theme settings (/admin/appearance/settings/platon) the two lines code:

@import url(http://fonts.googleapis.com/css?family=Exo+2:400,600,900&subset=latin,cyrillic,latin-ext);

body { font-family: 'Exo 2', sans-serif; }
