Non-ASCII paths and git-cvsserver

Hello,

I want to access a git repository via git-cvsserver. The problem is that 
the repository contains paths with umlauts. These paths come out quoted 
and escaped when checked out with cvs.

Test case:

#! /bin/sh

set -e -u -x

WORK='/tmp/gittest'
FILE=$'\303\244'

mkdir "${WORK}"
mkdir "${WORK}/git"

#trap 'rm -r "${WORK}"' EXIT

cd "${WORK}/git"

git init-db
git repo-config gitcvs.enabled 1
git repo-config gitcvs.logfile "${WORK}/git/.git/cvslog.txt"

touch "${FILE}"
git add "${FILE}"
git commit -a -mx

cd "${WORK}"

CVS_SERVER='git-cvsserver'
export CVS_SERVER

cvs -d ":fork:${WORK}/git/.git" co master

ls master

### end


This is what I get:

+ WORK=/tmp/gittest
+ FILE=$'\303\244'
+ mkdir /tmp/gittest
+ mkdir /tmp/gittest/git
+ cd /tmp/gittest/git
+ git init-db
defaulting to local storage area
+ git repo-config gitcvs.enabled 1
+ git repo-config gitcvs.logfile /tmp/gittest/git/.git/cvslog.txt
+ touch $'\303\244'
+ git add $'\303\244'
+ git commit -a -mx
Committing initial tree 23d6145738bba135994775c19d6e8ae707d399ee
+ cd /tmp/gittest
+ CVS_SERVER=git-cvsserver
+ export CVS_SERVER
+ cvs -d :fork:/tmp/gittest/git/.git co master
cvs checkout: Updating master
U master/"\303\244"
+ ls master
"\303\244"  CVS


I do not speak perl so can anyone help?
