I take it you are trying to restore onto a different OS platform with
different locale naming conventions. The easiest way to deal with it
probably is to edit the dump file and change "C.UTF-8" to "C.UTF8"
everywhere. (Manually editing an 8G dump file might be no fun, but
"sed" should make short work of it.)
