The behavioral description sounds fine, but I was eagerly awaiting your
description of exactly how you'd test for compatibility or search for
a compatible encoding ... without that algorithm the whole thing's moot.

BTW, what happens if there is more than one apparently-matching
encoding?  (It might be best to error out in this case, on the theory
that we evidently don't have a correct matching.)
