Can't font customize rendering for different combinations, how 
it's done for ligatures? The problem I see maybe not all text 
rendering engines support this. If the font doesn't assign a 
ligature, it will become a bunch of radicals, hopefully it will 
still be understandable, which can be better than unknown 
character displayed today.
