Hi there, I recently finished working on my first custom font, it's an alternate English alphabet I decided to try and make into a working font for fun.
I put it together using FontForge, it uses a set of alt-characters and alt-lookup tables which I've managed to get working in the app, you can see it automatically calling the correct alt-characters while typing in the metrics window picture here:



When I generate the font to a .ttf the alt characters show up correctly in the Windows Font Viewer as well:

However when I test out the font in any other app like Word the alt character lookups don't work at all, so it looked broken like this:

I'm completely stuck at this point, I'm a total novice with this stuff.. I'm really hoping someone can help point me in the right direction to get this working. Here's a picture of what my lookups in FontForge look like in case it helps:

Thank you very much for your time. Please let me know if you'd like me to PM you a copy of the .sfd file for this font.

That did it, thank you so much, I can finally start doing stuff with my font! Here's what it looks like on the opening of the declaration of independence:
Cheers!
