[Jani Uusitalo]

Public bug reported:

== Background ==

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

$ locale
LANG=fi_FI.UTF-8
LANGUAGE=fi:en
LC_CTYPE=fi_FI.UTF-8
LC_NUMERIC="fi_FI.UTF-8"
LC_TIME="fi_FI.UTF-8"
LC_COLLATE=fi_FI.UTF-8
LC_MONETARY="fi_FI.UTF-8"

LC_ADDRESS="fi_FI.UTF-8"
LC_TELEPHONE="fi_FI.UTF-8"
LC_MEASUREMENT="fi_FI.UTF-8"
LC_IDENTIFICATION="fi_FI.UTF-8"
LC_ALL=


== 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
