How to use Google’s Noto web font for software in multiple languages

With regards to an accessibility concern, it looks like google Noto font is a good bet to use as it supports 800 languages.

Is it just a case of changing the css code? For example, from Arabic to Bengali below....

font-family: "Noto Naskh Arabic UI", "Noto Sans UI", sans-serif;

This is so the software can be internationally supported.
