>>> Is it possible that the å character is coming from a UTF-16 encoding and is not representable in UTF-8?

With a few modifications, you should see things start to get strange:

I don't think it's a packaging bug;
I tried with /usr/bin/git on macOS 10.11 (git version 2.10.1 (Apple Git-78))
and I also get a (different) error but the command does not fail
(I needed to change restore to reset):

$ ./test.sh

git=/usr/bin/git

OK
