With over 1,500 options for fonts, Google Fonts will more often than not have the font that you are looking for. If they don't have the exact font, they are bound to have one like it.
If you are looking to add a custom font to your site, you can find out how to that here:
Add a Google Font
To add a Google font to your site, go to Design Settings, and select the Fonts tab in the upper left.

To add the font you've selected, click on the SAVE button in the bottom right corner.
Congratulations! You've added a new Google font to your site!

Voila! Now you can be sure the font you're adding supports the language you need it to.
