Ok, so I'm back. I've mainly figured out the fonts (still don't understand how to specify a 4 digit unicode character but that isn't directly important anymore).
Now, I'm trying to get the VBA code to work correctly and cleanly. The bound field is now an integer field instead of yes/no.
Requirements:
1. Needs to be tied to the underlying field.
2. Is either checked (true/-1) or unchecked (false/0). No null. Default field value is 0.
I have an invisible textbox for moving the focus as needed.
Current check/textbox control settings: Locked, Enabled
Issues:
I can also click/hold and drag to select the underlying value.
You can also see the underlying value and cursor when clicking on it.
