[volunteergrid2-l] some strange error

[Shawn Willden]

Heh.  Yeah, this is an area where I disagree with Brian Warner about the
best way to handle backups.  His approach is to "fail fast" when he finds
something that doesn't make sense.  My backup tool (which doesn't work well
enough for me to suggest you use it) takes a different approach.  If a file
name isn't valid per the system encoding, it stores the raw bytes of the
file name and stores a flag that indicates that the name may not be
correct.  Then the restore process has the information it needs to try to
recover a usable name, or can defer the question to the user if need be.

But that's not what tahoe backup does.

What to do?  I don't know.  Can you write a script that fixes the encoding?

Here's a bug report discussion that includes a trivial Perl script:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=396295

If you're using WinSCP on the Windows side, Google turned up some
discussion about fixes on that side, too.
