Can not show Chinese folder & Song Title

[SundayDriver]

I've followed the Tutorial Installing MinimServer on a PowerQUICC Synology NAS on this forum, thanks Jones, I use BubbleUPnP Control Point to play songs, my critical problem is in the Library only can show song folders/titles in English, all in Chinese can not be shown, I've check the current Platform default charset is US-ASCII and tried to modify the /etc/profile, I added the 2 lines like this:
LANG=en_US.utf8
export LANG
After finished, I updated with the "source /etc/profile" command,
and then restart Minimserver, but it is still no change, so please help and thanks.
