If I had to guess, what you’ve described isn’t a problem. It’s common for css and js files to be pulled in from different locations including from entirely different domains. But I understand that you want to rule this out as a source of some problems.
With that in mind, I would recommend trying out a plugin I have called Real-Time Find and Replace. With it you can search for the non-www URL and replace it with the www version (this doesn’t change any files). If this fixes the problem, you can look for a way to modify the theme permanently if you desire. If not, you can dump the plugin and continue your search for what’s causing the problem the the entypo icons.
This didn’t fix my problem. Still looking for solution.

Use the ‘get_stylesheet_uri’ function: https://codex.wordpress.org/Function_Reference/get_stylesheet_uri
Replace the path to the style.css file with that function.
