CSS does that automatically. That's why most people are probably falling back to sans-serif.

When you specify a list of font families in CSS, the browser tries the first one. If it isn't available, it tries the next one, etc.

Personally, I'd say the best option to make the site look the same for everyone is to find a free font you like.
