Hello! Dear szaka:

I'm trying to get ntfs-3g to run in an embedded environment to access my usb drive
it works mostly great but i've noticed that national filenames are missing when
its mounted with NTFS-3G...

here is my kernel configurations
###########################################
#
# DOS/FAT/NT Filesystems

CONFIG_FAT_FS=m
CONFIG_MSDOS_FS=m
CONFIG_VFAT_FS=m
CONFIG_FAT_DEFAULT_CODEPAGE=437

CONFIG_NLS=y
CONFIG_NLS_DEFAULT="utf8"

i mount with ntfs:

#mount -t ntfs /dev/sda1 /mnt
#ls /mnt
english.txt d8-f.txt
^^^^there's chinese letters ,it's not correct but ok

then mount with ntfs-3g:
#umount /mnt
#ntfs-3g /dev/sda1 /mnt -o force
#ls /mnt

english.txt
^^^^FILE MISSING

I know that NTFS-3G uses the locale defined in the environment
But for some reason i can't set my national locale support in environment
If I dont care character conversion properly or not!
Is it possible to show my national filenames ?
If it's not ntfs-3g problem could you give some advices besides ask my distribution vendor?

thanks you very much!

#mount -t ntfs /dev/sda1 /mnt
#ls /mnt
english.txt d8-f.txt <==there's chinese letters ,it's not correct but ok

then mount with ntfs-3g:
#umount /mnt
#ntfs-3g /dev/sda1 /mnt -o force
#ls /mnt

english.txt ________ <==FILE MISSING

Did you check out http://ntfs-3g.org/support.html#locale3 ?

Yes, I checked that link already. I know if set correct locale everything will be fine.

However I'm running on a embedded system, it will consume too much memory if I put locale data (including Asian countries) into it.

Actually we have a browser application running on the system, we don't expect the file/folder name show correctly on the console. It can be just a hex string and let the browser do the parsing/render job.

So I'm wondering if it's possible to let ntfs-3g just ignore locale data and just show the raw hex string on file/folder name, instead of showing nothing when locale is not setting properly.

Ok, I see.

Unfortunately it can't show the raw hex string since it includes zeros which would mean end of file name, so you wouldn't get the real file names. The data must be bijectively converted to something.

Two potential solutions:

1) Using iconv(3). I've played with it but needs more work and may not be the optimal solution.

2) Built-in conversion support, compile and run-time settable. This wasn't tried yet.
