Hi,
Here: http://linux.die.net/man/8/mount.ntfs-3g I read that:
“locale=value
This option can be useful when wanting a language specific locale environment. It is however discouraged as it leads to files with untranslatable chars to not be visible.”
OTOH here: http://www.tuxera.com/community/ntfs-3g-faq/ I read:
“If the locale environment is not setup correctly before mount then glibc can’t convert some filenames, so they are not visible and the directory is indeed not empty.”
This sounds somewhat contradictory - discouraged to use it but if it is not setup correctly… 
Should I use the locale option or not? Currently in /etc/fstab all NTFS partitions have locale=en_US.UTF-8, not sure what this gives or takes.
