I’m on a different machine now: the problem affects linux x86 and
pdftotext as well. Also, in xpdf I get smallcaps copied as
uppercase instead of lowercase.

I’m quoting from the changeset, so the “-” lines indicate the
good version.

Weird. Here’s a PDF of the code I posted compiled with version

I definitely get   from this
one. The characters are mapped from the private use area:

Can someone reproduce it at all?
