bundle and cat should both be exact.  They both emit bytes, not
characters.  So strict is wrong; output must not be treated as
characters and re-encoded.

With bundles, the metadata is utf-8 encoded, and the diffs are in
whatever encoding each file is in.

Cat's purpose is to output a file, so again, it's bytes.

I'm surprised it's exact, but maybe the reason was so that when you
include its output in a file, you get the same result on every platform.
