Hi,
Nautilus shows "invalid encoding" for some files with special characters.
The files are remount as read-only.
The others are without rw problem.

Some information:
HTML Code:
~$ cat /etc/fstab 
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda2 during installation
UUID=d95d3765-76ae-4388-893e-cc0e823f55f6 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sda1 during installation

HTML Code:
~$ cat /etc/mtab | grep sdb

HTML Code:
~$ locale -a | grep fr

HTML Code:

You will be a great help to me.
