Store files with Japanese characters in file name in msysgit

I'm using a German Windows XP and created a file name with Japanese characters in the name (どうもありがとうミスターロボット.txt) using the Windows explorer. msysgit console just shows question marks:

$ git version
git version 1.7.2.3.msysgit.0

$ git status
# On branch master
#
# Initial commit
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       ????????????????.txt
nothing added to commit but untracked files present (use "git add" to track)

What should I do to make msysgit handle this file?

Issue 374 of msysgit refers to:

• issue 358 (about switching the codepage used in a DOS windows)
• issue 369 (about installing a console window to use a True Type font)

So maybe the options discussed in those threads can help here.
