I suppose this is an adequate solution, but it*’*s also needlessly
convoluted in comparison to RIS where good fallback behaviour just happens
automatically with only the most bare-bones font feature imaginable, i.e.
simply displaying single characters one after another as they would appear
anyways. It is also questionable whether most vendors are going to employ
such system in the first place.
