I tried about five different fonts, and none of them worked. The one that I'm trying to use I've seen used in other layouts, so I don't think it's an issue on IJ's end? I really don't know for sure, though.
I've checked and double checked, and I can't find anything else that would be messing with it. Maybe I'm just missing something? Here is the code, with the edits that I made to it, if you want to take a look at it.
