Re: [Libguestfs] 【help】why not support show ing filename containing chinese characters with the ls f unction?



Hi,
    I tested again!
    The result is as follows:
==================================
    [malei xen-test2 ~]$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

[malei xen-test2 ~]$ guestfish --rw -a /home/malei/d.img -i

===============================================
Does it have something to do with the LANG environment variable or the disk img which is not bootable?

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 "/马磊"
 $ guestfish --ro -a chinese-chars.img -i

What are your language settings, eg. the locale and the environment
variables $LANG etc?  You can find out by running the 'locale'
command:

 $ locale
 LANG=en_GB.UTF-8
 LC_CTYPE="en_GB.UTF-8"
 LC_NUMERIC="en_GB.UTF-8"
 LC_TIME="en_GB.UTF-8"
 LC_COLLATE="en_GB.UTF-8"
 LC_MONETARY="en_GB.UTF-8"
 LC_MESSAGES="en_GB.UTF-8"
 LC_PAPER="en_GB.UTF-8"
 LC_NAME="en_GB.UTF-8"
 LC_ADDRESS="en_GB.UTF-8"
 LC_TELEPHONE="en_GB.UTF-8"
 LC_MEASUREMENT="en_GB.UTF-8"
 LC_IDENTIFICATION="en_GB.UTF-8"
 LC_ALL=

If you can reproduce this issue, please file a bug:
