Oops. There was a confusion and I made an error in the description of the problem. The files which were extracted as iso-8859 are those in the solaris machine and I can see them correctly using kubuntu through ssh by changing the default charset as described in my previous post.
In kubuntu, it seems that tar tries to encode them in UTF8, but it doesn't manage to do that with the accented characters and therefore only "?" are still shown. -- problems with character set encodings https://launchpad.net/bugs/74463 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
