Setting different fonts for database

Hi,
My site is multi languages and I’ve made the language button and database.
Now I’d like to set different fonts for each language.
How should I do?

For example I want to use font “Georgia” for English and other font(or my uploaded font) for French, apply to all text or button.
Thank you!

Hi,
How would you know which language is being used?
Do you want to save a user input and display it with matching font? or do you want to change all site’s elements?
