Question [Q] Cyanogen in Archos 101 could not read Chinese(GB-5) file name in file manager

I have successful to install Multi-boot and Cyanogen (openaos-gingerbread-gen8-20110708_183154.img.gz) in my ARCHOS 101!

but it could not read Chinese(GB-5) file name in file manager (always show "xxxx " instead of "Chinese' wording?) even I already changed the "SETTING" language to Chinese(GB-5)?

Anybody can help me to solve the issue???

P.S: My another UrukDroid 1.1RC1 and Archos firmware 2.3.81 do not have such kind problem?
