there go:

function sienna_fonts_url() { $fonts_url = ''; $font_families = array(); $font_families[] = 'questrial'; $font_families[] = 'open sans:400,600,700'; $font_families[] = 'playfair display:400,700'; $query_args = array(     'family' => urlencode( implode( '|', $font_families ) ),     'subset' => urlencode( 'latin,latin-ext' ), ); $fonts_url = add_query_arg( $query_args, 'https://fonts.googleapis.com/css' ); return esc_url_raw( $fonts_url );
