The problem is I'm not sure what manifest's item.data is supposed to be. The docs for calibre.ebooks.oeb.base.Manifest.Item.data say "it should be a str type", but that doesn't seem to make sense for a binary file (at least for python3). More likely it should be a string_or_bytes, and consumers should check whether the item data is an instance of bytes (which it should be for image files that aren't representable as decoded bytes).
