Ah right that's the decomposed form.
HFS must use that for normalization of file names.
Using that I can reproduce your issue with an incorrect locale:

# LC_ALL=ko_KR df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       100M  120K  100M   1% /root/�??�?��??�?�
# LC_ALL=ko_KR.UTF-8 df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       100M  120K  100M   1% /root/무제


I.E. It looks like you have the wrong locale settings for the df command.
Please try setting LC_ALL as above, or otherwise setting UTF-8.

thanks,
