[jimmeak]

If you wants to add new font into the project, there will be a css for that.

To get the proper files this heroku page is extremely helpful
Heroku Google Webfonts Helper

To get czech characters, there must be available version latin-ext.

Customize the folder prefix to /static/fonts/<font-name>/ so you can save those files in this folder then.

The generated CSS add to file /static/fonts/fonts-definitions.css.
