Interesting. The '\x{fffd}' part is clearly wrong even though the process
survives.  I can reproduce it. It's sensitive to the (seemingly unrelated)
command line arguments.

Running with valgrind:

  % LC_ALL=C valgrind perl -I. Makefile.PL INSTALLDIRS=vendor create_packlist=0

So this seems like a bug in either Encode or Perl itself. Will investigate
more later.
