No, not according to my reading of the code.  (The telltale sign is
that "C-h C" tells you utf-8-emacs has the usual 3 EOL variants,
something that makes no sense for the internal representation.)  If
something like "dump internal representation" coding-system is needed,
we will have to add it, I think.
