Libguestfs - May 2012 - 【help】why not support showing filename containing chinese characters with the ls function?

Hi,everyone:
    As the subject says, why chinese characters are shown as '?' by
using
ls function?
    Did anyone encounter the same problem and does resolution exist?
    Looking forward to your reply. Thanks in advance.

I tried this, and it works for me:

  $ qemu-img create -f qcow2 -b /dev/vg_pin/F16x64 chinese-chars.img
  Formatting 'chinese-chars.img', fmt=qcow2 size=21474836480
backing_file='/dev/vg_pin/F16x64' encryption=off cluster_size=65536
  $ guestfish -a chinese-chars.img -i touch "/??"
  $ guestfish --ro -a chinese-chars.img -i

BTW, another problem about mount:

[malei at xen-test2 ~]$ guestfish --rw -a d.img -m /dev/vda1:/:utf8
libguestfs: error: mount_options: you must mount something on / first
guestfish: '/dev/vda1' could not be mounted.  Did you mean one of these?
/dev/vda1 (vfat)
/dev/vda2 (ntfs)
/dev/vda3 (ntfs)
/dev/vda4 (unknown)
/dev/vda5 (vfat)
/dev/vda6 (vfat)
/dev/vda7 (ntfs)
