如何找出当前文件系统使用的charset编码以及如何将其更改为UTF-8？

编辑：

这是mount的输出：

@H_403_5@/dev/sdb6 on / type ext3 (rw,relatime,errors=remount-ro) tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) /proc on /proc type proc (rw,noexec,nodev) sysfs on /sys type sysfs (rw,nodev) varrun on /var/run type tmpfs (rw,mode=0755) varlock on /var/lock type tmpfs (rw,nodev,mode=1777) udev on /dev type tmpfs (rw,mode=0755) tmpfs on /dev/shm type tmpfs (rw,nodev) devpts on /dev/pts type devpts (rw,gid=5,mode=620) fusectl on /sys/fs/fuse/connections type fusectl (rw) lrm on /lib/modules/2.6.27-11-generic/volatile type tmpfs (rw,mode=755) securityfs on /sys/kernel/security type securityfs (rw) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,nodev) gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon (rw,nodev)

这是“cat / etc / fstab”的输出
