I think that the `binary' (better not call it "no-conversion" because it's a misnomer if one of the ends is multibyte) coding-system should default as much as possible to unibyte buffers and unibyte strings (so it indeed does "no conversion" in that case). > PS. Another idea is keep archive files in a unibyte buffer > and have the file listing part in another multibyte buffer. Yes. I've introduced the new buffer-swap-text primitive specifically to make that possible. Stefan
