I've installed japanese fonts
sudo apt-get install ttf-takao-mincho
and I mounted my drive specifying utf8
sudo mount -t vfat /dev/sdc1 /media/HERMES -o uid=1000,gid=1000,iocharset=utf8,dmask=027,fmask=137
but japanese file names show up as ??? in terminal and on my samba share, it shows up as numbers+characters.
How do I fix this?
