Insert icon directly in text?

So far, when I want an icon and a text together, I have to group them in a container.

A easier way to achieve this is to directly add the icon inside the text element.

For instance, using FontAwesome, adding something like fa-check will render the “check” icon.

Is there anyway to do this?

I know about custom code, but that only works on a live site (I’m in development phase still).

It work with SF Symbol since i tried work perfectly, just none-mac user won’t be able to see it.
I guess it depend on the librairy and how it is installed/rendered on client-side
