Remove a file with a strange name from git

Question

I have a file that managed to get itself named:

# file's name (both lines)
companies.yml
companies.yml

# entry in my git working tree
"test/fixtures/companies.yml\342\200\250companies.yml"

For annoying reasons, the working tree on this particular project is full of other files that still need organizing. I would like to get the above entry out of there, but when I try git add "test/fixtures..." or git rm "test/fixtures..." it fails:
fatal: pathspec 'test/fixtures/companies.yml\342\200\250companies.yml' did not match any files

How can I deal with this?

Git is printing the literal octets of the UTF-8 encoding of the filename because they are non-ASCII characters, and printing them as octal escapes. However, your shell does not understand them and is sending literal backslashes and digits to the git command when you cut and paste, so you're actually entering a different filename.

Either use tab-completion after typing test/fixtures/companies.yml (if your shell supports this) which will enter the actual characters or a wildcard in place of the escapes thus test/fixtures/companies.yml*companies.yml. The latter might, but probably won't, match other filenames.

Another possibility is to just rename the file to something more sane, of course, and then use git add -u / git add . to get git to notice the rename.
