Issue using Font outside of Photoshop

I created a bitmap font for use in my game within Unity but when I try using it none of the glyphs show up, it works as intended within photoshop, checking it with Windows Font Viewer it shows the font as blank, what’s the issue and how do I fix it?

Hello ChromoDev and welcome to this forum.

I hope that will help you:
