I need to display special characters for a program, I used to do this with setting the textbox' font to a special one (ti83pluspc if you're wondering which). But I want to create a new one using the characters of Courier New but the ones I don't need deleted from it and the ones I need but don't exist in there added to it.

I already tried to do this but when I tried to use that font for the textbox it didn't show up in the list...

Got it working somehow...
