Nautilus can't display Chinese volume label correctly.

Binary package hint: nautilus

I'm a Chinese user and my English is not good.
If there are Chinese characters in the volume label,they will not be displayed correctly.They will be displayed as "??".
I used gparted to rename the volume,but it doesn't work at all.
And It doesn't happen in Ubuntu 9.04.
If you can understand Chinese,read the following:
===================>
如果有中文字符在卷标里的话，他们将不会正确显示，而是显示成一堆"?"。
我用gparted改过卷标，可是没有用。
Ubuntu 9.04时还没有这个问题。
-------------------------------------------------
Translation:
If there is Chinese characters in the volume label, they won't be displayed correctly, and several "?" will be showed instead.
I've tried to change the label using gparted, but turns out to be useless.
There wasn't such problem with Ubuntu 9.04.
