It'd be great if you could get me / point me to a vfat image that
contains Chinese character filenames.  One way (assuming this image
does not contain sensitive data) is:

  guestfish --ro -a /home/malei/d.img
  ><fs> run
  ><fs> download /dev/vda1 - | xz --best > /tmp/vda1.img.xz

and then send me the file /tmp/vda1.img.xz.
