I've successfully added new fonts to the default selection of google fonts in the theme options, but I realized that it will get the latin variant of the fonts and I need the latin-ext (my language is hungarian). To overcome of this limitation I finally edited assets.php and extended the query_args var to include the subset param: $query_args = array( 'family' => $google_fonts, 'subset' => 'latin-ext,latin' ); I suggest you to add a checkable font variant selection to the configuration panel to ease the process to have nice "exotic" characters from google. ;)
