So while I can't vote on this, I think we should revisit this. Perhaps look at how is doing it. They allow you to import fonts which is really nice (as well as themes). And there's no need to use external third-party apps to do it. I believe their app is open source too so that would probably be helpful.

I would definitely love to see this, probably for all languages. Is there anyone who want want trailing whitespaces left? If so, at least have it be an option where one can enable or disable it so it removes trailing white space when you save the file or something.
