For Windows, I have currently nothing. This would probably need to have some custom drawing code in the text rendering.
So maybe FTC?

If it isn’t in the Windows toolbox like it is on the Mac, I’m not interested. It will just be a feature difference between the Mac and Windows.

Feel free to read in MSDN docs:

Thanks. I don’t see it there though, and a search revealed nothing.
