Thanks Tom,
Dumped in Ubuntu 22.04_1 and restore attempted using Ubuntu 22.04.3
Editing the dump file to C.UTF8 didn't solve the problem.
The default for the database was en_AU.utf8 so I should have changed the
collation to that, but it was one field in one table of superseded data, so I
just erased the collation from that field.
Still no idea on how it came to be there.
Cheers
Tony
