Quite the contrary: it's the only right thing to do because we're comparing
two pieces of buffer (not file), so we want to deal with *any* char (even
those that will not be savable in the current buffer-file-coding-system) and
both files that we pass to `diff' will be temporaily created by ediff
anyway so that will also ensure they both use the same encoding.
