@Devon: okay, I guess the PDF is misbehaving because it uses some other font -- a []AV-based layout -- than today's standard: "APL385 Unicode" -- and I haven't got it installed. As for the RTF, TextEdit has used what it considers the "nearest" font and shows me a garbling (which I just happen to recognise!) with '@' for the lamp symbol and '„' for the left-arrow.
I've spent thousands of hours decyphering this sort of nonsense in archived papers. "APL385 Unicode" really is the way to go. Or (of course) J! PM me for your mailbox, and I'll reply with my scanned PDF from an actual Vector hardcopy as an attachment. Can't get more definitive than that (...it was, after all, what was actually published).
