Details:
I didn't have a way of determing when strikethrough vs underline was happening.

I finally figured a somewhat hacky but legit as far as I can tell way to signal underline and strikethrough, which is to use a large value of thickness in the font metric.

Since we only support a thickness of 1 in a console app, this feels like a safe way to do it and shouldn't get in the way of anything.
