It sounds to me that this is more of a feature request than a bug at this point. If anyone disagrees, let me know, otherwise I'll reclassify this in a few weeks.

Caveat: I haven't followed this thread, but this sounds similar to bug #1183.
I believe that the #1183 thread ended with Eli asking Michael Kifer to have
Ediff let you know that the two have the same (or similar) content but different
coding systems and hence different byte sequences.
Perhaps that never got fixed/finished?

Presumably you'll get the same "one big hunk diff" if you use
ediff-files. Both ediff-files and ediff-directories work (as the name
implies) on files (and directories), not on buffers. While the two
buffers show similar (or even identical) contents, the corresponding
files are different (contain different byte sequences because of the
different coding-system).

Presumably you'll get the same "one big hunk diff" if you use
ediff-files. Both ediff-files and ediff-directories work (as the name
implies) on files (and directories), not on buffers. While the two
buffers show similar (or even identical) contents, the corresponding
files are different (contain different byte sequences because of the
different coding-system).
