invalid unicode (cdw)

hDUQUE · 03-17-2008, 11:58 AM

hi guys,
i am getting problems when trying to write some files to CD because of their names ... it says "invalid unicode", and stops the writing process.

in the other sense, from CD to disk, or from hard disk to hard disk, or to usb devices, there is not problem.

it looks like a configuration problem ...

any ideas ???

thanks in advance,

hector

i have fedora C6 in both my pc and laptop; same problem i those two machines :-(

You can sometimes get this problem when the file names contain letters not found in the English alphabet. I think that the solution is to tell Linux to use UTF-8 encoding on the CD-ROM. I have never done that but I think this may be the solution:

Quote:

For FAT and ISO9660 (used by CD-ROMs) partitions, option utf8 makes the system translate the filesystem's character encoding to UTF-8. For NTFS, nls=utf8 is the recommended option (utf8 should also work). Add these mount options to filesystems of these types in your /etc/fstab to make them mount with the correct options. A fragment of /etc/fstab might then look like this (other options may vary depending upon your setup):

/dev/hda2 /mnt/c ntfs defaults,ro,nls=utf8 1 0
/dev/hda3 /mnt/d vfat defaults,quiet,utf8 1 0
/dev/cdrom /mnt/cdrom iso9660 defaults,noauto,users,ro,utf8 0 0
# If using supermount, add "utf8" to the options _after_ two dashes, e.g.
#none /mnt/cdrom supermount fs=iso9660,dev=/dev/cdrom,--,auto,ro,utf8 0 0
/dev/fd0 /mnt/floppy auto defaults,noauto,users,rw,quiet,utf8 0 0

After you modify /etc/fstab, you should remount the filesystems in question by issuing a mount -o remount /mnt/mount-point command for each of them. Non-ASCII characters in filenames on those filesystems should now be displayed correctly again. Note that this requires the kernel to be capable of converting between character sets, so support for UTF-8 must be compiled in or available as a module. This option is available in "File systems"->"Native Language Support"->"NLS UTF-8" in the kernel configuration program.

hi jailbait, thanks for asnwer,

my fstab looks like that

Quote:

/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
LABEL=/home /home ext3 defaults 1 2
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/dev/sda1 /home/backMUSIC ext3 defaults 1 1
/dev/cdrom /mnt/cdrom iso9660 defaults,noauto,users,ro,utf8 0 0

but, my gnome cd creator (fedora c6) does not mount with those parameters ...
am i doind something wrong?

regards,
hector

No, I think Nautilus CD creator is doing something wrong:

Quote:

Nautilus CD Burner checks names of files added to its window for UTF-8 validity. This is wrong for users of non-UTF-8 locales. Also, Nautilus CD Burner unconditionally calls mkisofs with the -input-charset UTF-8 parameter, which is only correct in UTF-8 locales.

The general rule for avoiding this class of problems is to avoid installing broken programs.

http://www.linuxfromscratch.org/blfs...le-issues.html

Read the section starting with: "The Program Uses or Creates Filenames in the Wrong Encoding".

I think that you should try some other CD burner like k3b or cdrecord.
