Description Michał Kosmulski 2004-10-08 18:41:43 UTC

Version:           0.11.17 (using KDE KDE 3.3.0)
Compiler:          gcc 3.3.4 
OS:                Linux

I record my CDs with both Joliet and RockRidge extensions turned on, so I expect that all filenames be written to the disc using Unicode characters. My system uses a UTF-8 locale. When there is a file containing non-ASCII characters (e.g. Polish diacritics) in its name and 'Verify written data' is enabled, verifying the recorded disc always fails, even if a manual md5sum check confirms that the disc was recorded correctly.

Comment 1 Michał Kosmulski 2004-10-12 20:54:22 UTC

Additional info:
I use supermount (supermount-ng.sourceforge.net) for mounting the CD-burner, the line in /etc/fstab is:
none /mnt/cdrom supermount fs=iso9660,dev=/dev/cdrom,--,auto,ro,utf8  0   0
but I also tested with a normal mount:
/dev/cdrom /mnt/cdrom iso9660 defaults,users,noauto,ro,utf8  0  0
and got the same results. Verifying fails, even though I can manually check that all files were recorded correctly, with the message 'Could not find XYZ', where XYZ is the name of one of the files whose names contain non-ASCII characters. I burn with all 'compatibility' options ('allow 31 char names' etc.) disabled.

sounds like a dup of bug 83315

Comment 3 Sebastian Trueg 2005-12-10 13:54:34 UTC

SVN commit 487359 by trueg:

Copied iso9660 filename generation code from mkisofs. With it K3b is able
to determine the iso9660 names generated by mkisofs and use them for data
project verification.
The result is: no charset problems anymore.
