Yes. And from what I've read
(http://stackoverflow.com/a/8259610/615245), non-ANSI encoding support
was added piecewise, so maybe the relevant code still hasn't settled.

This makes sense. I don't think anyone's likely to encounter a source
file with characters that are encoded differently between utf-8 and
utf-8-emacs, but I guess the latter is unspecced, so it could change in
the future.
