Limit font subsets

Hello @sebfck

The @font-face calls may include all languages, but they also include unicode-ranges.
As a result, only the characters used by your website are loaded. Even though the styles contain references to files for all languages, the browser only loads the ones it actually needs.
That is because we have carefully chosen the user-agent we use (you can see it here: https://github.com/kirki-framework/kirki/blob/0e0a09cdae56971d1dacdb778b109343594c92f0/modules/webfonts/class-kirki-fonts-downloader.php#L184) so it’s the only user-agent that supports unicode-ranges (to improve performance) and woff files (for IE11 compatibility).
Removing references to other languages will not save you any data.

I hope that helps!

Thank you for the explanation!
