I would strongly suggest to give us the option to pick the translated fonts. There are many fonts which does not support all font types. For example the Greek language. We have only few options in font choice. So when I site is in English and I would like to translate it to Greek, to have the option to pick the Greek font (some Google Fonts have this option).
Best,
Hi there, @Better_Host and welcome to the Community 
Many thanks for sharing your idea with us! If more users support this idea, we’ll try to consider it in the future 
As for now, I’ll be happy to check if there is a custom solution for you. You’d like to set the specific font only for the Greek translation, right? If it is, could you please specify the name of the font you’d like to use?
