hmmm… definitely not out of the box so far (as i know).
would assume it demands at least some custom css (or even more…) – better to use some plugin maybe. there has been some ‘tinymce custom styles’ or ‘tinymce custom formats’ -plugin somewhere that does the trick.
That’s a Google Font. It will only work if it’s selected in the Customizer somewhere, or if you embed it using the instructions Google Fonts give you. You can insert their code into the wp_head hook in GP Hooks.
