How to handle Chinese file name correctly in Mldonkey

1. I have Mandriva and locale of Mldonkey isn't printed in log file. Therefore I checked the command that starts mldonkey service (default is /etc/init.d/mldonkey). I saw the following
   daemon --user mldonkey --check mlnet $NICE $mldonkey $params >/dev/null 2>&1 &
   and I changed it to
daemon --user mldonkey --check mlnet $NICE $mldonkey $params >/dev/null 2>$LOGFILE &
   
2. After I restart Mldonkey servcie, I check the log file again(default is /var/log/mldonkey.log). I saw the following
   [cO] Language en_US, locale ISO88591, ulimit for open files 1024
3. The function daemon is defined in /etc/init.d/functions and the following is invoked
   su -s /bin/bash - $user -c "$corelimit > /dev/null 2>&1 ; $*"
   which means mldonkey service is started in a login bash shell of user mldonkey and the file .bash_profile in its home directory should have the correct environment variables set.
4. I added the following line to the file /var/lib/mldonkey/.bash_profile (or ~/.i18n)
   export LC_ALL=zh_CN.GBK
   I didn't set the above to zh_CN.utf8 since my samba also had the line unix charset = GBK in smb.conf
5. After restarting the mldonkey service, the following is shown in the log file and Chinese file names are handled correctly (instead of using underscores everywhere)
   [cO] Language ZH_CN, locale GBK, ulimit for open files 1024
