Reporting from Xenial, but this is currently reproducible in Artsy too.

== Test case ==

$ git init test
$ cd test
$ echo ”foo” > bär
$ git add [hit tab key]
$ git add \”b\\303\\244r\” [hit enter]

== What happens ==

fatal: pathspec ’”b\303\244r”’ did not match any files

== What I expect to happen ==

For the filename to be correctly completed, like with ls:

$ mkdir test2
$ cd test2
$ echo ”foo” > bär
$ ls [hit tab key]
$ ls bär [hit enter]
bär
