The only thing it can do is output the replacement character U+FFFD,
or `?', or characters in the range U+DC80..U+DCFF.  I tend to think
that `?' is the best alternative.

So we should have a different encoding symbol for these two variants.

I still maintain that VM should do better in this case.  I don't think
we have a clear idea of what happened in this particular crash, so
perhaps is too soon to forget about VM's part.
