I think you can just replace "\0".to_owned() with "=".to_owned()

Which line are you referring to?
Also I'm confused because this PR doesn't have a line containing the change you propose!?

Sorry about that, line number 544 in original file (line number 553 in the PR file).

Oh thanks for mentioning this, I didn't notice that.

I don't know why

Nice! The only difference with GNU I can still find is:

$ # GNU
$ echo "a=b" | cut -f2 --delimiter=
a=b
$ # uutils
# echo "a=b" | cut -f2 --delimiter=
b

But I guess that's not useful anyway.

I noticed that -d '' means '\0' (NULL character) in GNU's cut, please see:

I tried these commands in my zsh (ArchLinux):

$ echo 'ab\0cd' | cut -f 1,2 -d '' --output-delimiter=Z | hexdump -C
00000000  61 62 5a 63 64 0a                                 |abZcd.|
00000006
$ echo 'ab\0cd' | uu-cut -f 1,2 -d '' --output-delimiter=Z | hexdump -C
00000000  61 62 00 63 64 0a                                 |ab.cd.|
0000000

Using -d '' to set the delimiter to = may not be a good idea.
