I like Rygle's proposed solution. Compatibility is a good thing here. I'd also suggest adding mapchars,iocharset=utf8 as default options for CIFS mounts for the same reason. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/230906 Title: Using special characters in filenames prevents Windows from opening To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntfs-3g/+bug/230906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Some good news on this bug. I put up a comment on the NTFS-3G forums and got a very positive reply from Jean-Pierre, one of the lead programmers for NTFS-3G; I asked... [QUOTE] Could you please include a switch in NTFS-3G to allow a workaround for this Windows limitation? (i.e. to turn off use of special characters in order to allow compatibility with Windows for the many users who wouldn't have a clue how to re-mount/export their NTFS filesystems using Samba) [/QUOTE] And Jean-Pierre replied... [QUOTE] This is available in the release candidate advanced ntfs-3g-2010.5.16AR.1, see http://pagesperso-orange.fr/b.andre/advanced-ntfs-3g.html The option to use is windows_names, documented in the manual of the said version.

[Bug 230906] Re: Using special characters in filenames prevents Windows from opening
@eapache ever since XP, Windows has supported the notion of subsystems within the operating system. This allows support of, for example, a POSIX subsystem within Windows. In theory, this is a useful feature, but really almost no one uses any other subsystem except for the standard Windows NT one. So ntfs-3g can't make the assumption that a certain character is invalid for a filename, since even if it's invalid in one subsystem, it may not be in another. The best way to fix this bug would be to add some kind of check in nautilus (or dolphin, etc.) so that if it detects you are trying to write a file to an ntfs filesystem, it warns you. This could be expanded to support other filesystems as well. For example, if you have some filesystem for BeOS mounted that doesn't support some random character, nautilus can warn you before you write to it. This would be kind of a big fix though. Anyone want to draw up a blueprint or do a brainstorm for this or otherwise take the lead? -- Using special characters in filenames prevents Windows from opening https://bugs.launchpad.net/bugs/230906 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 230906] Re: Using special characters in filenames prevents Windows from opening
The Support page on the NTFS-3G website doesn't make a whole lot of sense to me. This isn't a case of certain applications on Windows not supporting the special characters, this is a case of the entire filesystem layer on Windows not supporting these characters. While it is technically not the fault of the NTFS-3G driver, it can still cause problems for the uninformed user who just wants to share files between OSes.

We should do with those invalid chars just like the vfat module is doing with invalid (on VFAT) Unicode chars. It's better to replace them silently than to prevent Windows from reading them.

[Bug 230906] Re: Using special characters in filenames prevents Windows from opening
http://ntfs-3g.org/support.html#posixfilenames2 Why does the driver allow special characters in the filenames? NTFS supports several filename namespaces at the same time: DOS, Win32 and POSIX. While the NTFS-3G driver handles all of them, it always creates new files in the POSIX namespace for maximum portability and interoperability reasons. This means that filenames are case sensitive and all characters are allowed except '/' and '\0'. This is perfectly legal on Windows, though some application may get confused. If you find so then please report it to the developer of the relevant Windows software. Workaround: If case insensitivity handling and/or restriction of special character usage is desirable then you may export the NTFS volume via Samba which supports this functionality the same way as it does for other POSIX file systems.

[Bug 230906] Re: Using special characters in filenames prevents Windows from opening
A bit of googling and testing shows that the null character is invalid in ext2, and that it's silently removed from files: $ echo ~/foo$'\0'bar $ ls ~/foobar /home/andrew/foobar If these are actually valid characters in the filesystem, it seems inappropriate to call this a bug anywhere in Linux. What if my digital camera only supports FAT but I want to create a file Me my friends.jpg? Reading the open(2) man page, it's not clear to me that the kernel has any concept of rejecting illegal filenames: the null character is silently discarded and '/' is treated as a directory separator. However, mount(8) shows that there's a uni_xlate option for vfat which translates Unicode characters that can't be represented in a FAT filesystem. If you don't mind rousing the kernel gods, this problem could be fixed by adding the specified characters to those that uni_xlate handles, and by adding uni_xlate to NTFS-3G. This has the advantages that it's relatively transparent to the user and doesn't create weird side-effects like filename collisions. However, it needs to be explicitly turned on, and doesn't help with the (admittedly rare) case of people wanting to read funnily-named files in ext2-on-Windows FSs. Alternatively, bugs could be filed against all of the major graphical filesystem browsers to add a warn on Windows-illegal characters mode. One problem with this is that it creates annoying are you sure? boxes that people will ignore then complain about the non-existence of. Another problem is that there will have to be a line drawn between programs that support this feature and programs that don't - it'll be a long time before `cp` gets such a feature, for example. Users crossing that line will face significant confusion as programs on the other side of the line do the wrong thing (from that user's point-of-view). -- Using special characters in filenames prevents Windows from opening https://bugs.launchpad.net/bugs/230906 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
