Characters blank in finished font

[zanestein]

I created a symbol ttf in FontCreator 11.5. It shows all the symbols clearly in FontCreator. It only lists one invalid character.
But when I go to properties it does not show a glyph assigned to the character.

And when I export the font and install it on a computer, there are no characters showing.

What can I do to fix this? i've created numerous fonts before without a problem.

I have tried setting up the font twice, once on a Win 10 pc and then on a Win 11 pc. No luck.

Help!

Nevermind. I figured out the problem. User error.
