### Please describe the problem.

The "add" command silently ignores all files and directories with non-ascii characters.

### What steps will reproduce the problem?

I created empty repository (git init, git annex init). I created some files with ascii and nonascii file names (hacky.txt, háčky.txt).

git annex add . correctly adds only hacky.txt.

git annex add "háčky.txt" does nothing.

### What version of git-annex are you using? On what operating system?

git 1.9.0, 
git-annex installer from 2014-03-06

Windows XP and 7 with czech localization. CP1250 is used for czech characters on windows.

### Please provide any additional information below.

    $ ls
    hacky.txt  h????ky.txt
    $ git annex add .
    add hacky.txt ok
    (Recording state in git...)
    $ git annex status
    D h├í─Źky.txt

According to https://github.com/msysgit/msysgit/wiki/Git-for-Windows-Unicode-Support ls prints junk, but only to console.

    D:\anntest>git annex add "háčky.txt" --debug
