[file system mount issue] NTFS

I’m about to back up some datas from NTFS partitions but some files are UTF8 (locale fr_BE.UTF-8 as described in fstab).

I tried the command

mount.ntfs -o locale=fr_BE.UTF-8 /dev/sdb4 /source

But the system sent me message like /dev/sdb4 is not a valid NTFS partition…

mount /dev/sdb4 /source

works but I got ‘?’ and other translation codes in filenames in places of ‘é’, ‘è’ etc… that sucks…

I booted from a rescue disk in order to backup files prior to reinstall a 15.4 on this computer.

Sorry I dug in the meanwhile: mount -o iocharset=utf8 works…
