Yep. Using acroread 7.0.8 on Linux, copying this into the joe editor
(version 3.5) works just fine.

Apparently a bug in gnome-terminal. Copy & Paste works for me within
both joe and the KDE terminal (Qt: 3.3.4, KDE: 3.4.2 Level "b",
Konsole: 1.5.2); I tried with
echo <Unicode stuff from the second line> > foo
and checked the result afterwards. Since my SuSE version is quite
old, the console, the font display engine, and the programs disagree
on the widths of characters from the Ideograph Extensions (which were
too new to be implemented already, I presume), but this is a minor
issue.

Then you are doing something wrong, probably a misconfiguration. For
me, using CVS from 2006-Oct-03, the characters are copied correctly
(however, they can't be displayed and appear as empty boxes). I have
the following in my .emacs file:
(setq x-select-request-type 'UTF8_STRING)

Interesting. With Acrobat, everything is just fine. Using xpdf (both
version 3.00 and 3.01), I get those `U+D840' characters. So we have a
bug in xpdf (which probably doesn't support Unicode > U+FFFF yet -- at
least it doesn't handle surrogates correctly while working with the
cliboard of X.

Probably the same problem.

Please do so!
