That would mean that if, say, you were backing up your SE/30's hard
disk to your new Snow-Leopard-or-later Mac, some file names might look
corrupt in OS X. But if you later restored those files back to the SE/
30, they'd be okay again?

Good advice, but about 17 years too late for me. They're not funny
characters if you're Danish or French or whatever. Now if we'd known
this was going to be an issue in 1984 ....

If there's no way to preserve names, that would be a good second-best.
If I use Transmit on the old Mac as ftp client and turn on its "Don't
filter file names" option, the problem characters show up in OS X as
three characters, a percent sign and the two-digit hex code of the
character, like "%97", which is 151 in decimal. This is consistent and
predictable, at least.
Something like the old "Drop Rename" utility could batch-process file
names, searching and replacing strings. But it didn't make the switch
to OS X.

In Mail 4.1, at any rate, you can turn that off in the Edit-
Substitutions menu for mails you're sending. But if someone has sent
the email to you, I guess it's too late.

Yes I know. But this isn't about my particular problem with a G3/OS
9.1 Mac. It affects all pre-OS X Macs. None of them can afp file-share
to new Macs shipping today, or from now on.

I just tried that, and Safari sees the files OK and the names are
correct in the browser window. But you can only download files that
way, not folders, or whole folder structures. And any file names that
have åæø etc. characters get renamed with the server name. So "test
åæø.txt" becomes "192.168.1.2.txt". Also, Personal Web Sharing isn't
available to many vintage Macs.
This may not be a big problem for many vintage-Mac owners yet, but it
will become one as the percentage of Macs running Snow Leopard and
future OSes gets bigger.
