I thought that was probably it.
So yes, you'd need a version of realize that deals with IGNORE. (I
believe IGNORE only makes sense in the dialog, which is why realize
doesn't deal with it.) Also, you would probably want to get the font in
effect at the current cursor position, and realize against that. I
believe that GuiCharacter should have access to a BufferView, which has
a Cursor, which can get you the Font.
