Can't copy files with "foreign" characters in filename from NFS share

Greetings

Here's an odd problem I have when Finder-copying files over the
LAN from an NFS mount on a linux (Fedora Core 4) machine to my
Mac (G5, OS X 10.4.7).

Say there's a folder on the linux box that contains files that
have "foreign" (I'm in the US) characters, like, say, accented
characters and so forth, in their filenames. Then when I
Finder-copy that folder to the G5, the files with the "foreign"
characters in their names won't copy. Attempting to individually
copy such a file to the G5 results in the cursor turning into the
universal "denied" symbol, (circle with slash), and the copy
fails. It's not a permissions issue, because I have read
permissions on the files.

I can usually get around this problem by doing

$ cp -R folder-on-linux-box destination-folder-on-Mac

in Terminal, but sometimes this won't even work. In that case, I
have to (on the linux box) copy the problem files to another
directory, rename the files using only 7-bit ASCII characters,
and then copy those files over the network to the Mac.

Does anyone know a better way to get around this weird issue,
which I assume is a bug? Like making it to where a Finder copy
will work regardless of non-7-bit ASCII characters in filenames?
