Fonts not working or importing correctly

Hi, for the life of me I can’t figure out how to use fonts from my computer (Windows 10). All of my font files have a blue A rather than a black one on them, I think it means it is compressed but I’ve never had a problem with this before.

I’ve been making great progress with my project with some fairly advanced stuff - to hit a wall because of problems with fonts is a bit of a slap in the face!

Any help would be greatly appreciated.

Figured it, Unity doesn’t seem to like .fon (font) files, True Type work fine (.ttf)
