Everything Michael said sounds right to me. IMO, it would be OK for ediff-buffers, perhaps optionally, to report encoding differences *also*, but that's not what ediff-buffers is really about. It's about detecting textual differences: `foo' vs `fog'. If it cannot tell you that `foo' is different from `fog', and it only tells you that the two buffers are (somehow) different, then it is being less helpful than before, not more.
