Re: Force git diff to create a binary patch?

Jason Xu [off-list ref] writes:

Here are two small files with non-ASCII data, yet git diff considers
them text instead of binary.

Because it is based on heuristics, without a NUL in that short file,
the file may not be judged to be binary.

    echo '* -diff' >.git/info/attributes

would tell Git that they need to be treated as binary junk not
suited for textual diff (you'd need to tweak the pattern to your
need).
