That's because "UTF-8" is not a valid argument for binmode().

You want:

   $ echo 包 | perl -E 'STDIN->binmode(":encoding(UTF-8)") or die; while(<>) { s|\s+\n|\n|sg; print }'
   Wide character in print at -e line 1, <> line 1.
   包

or:

   $ echo 包 | perl -E 'STDIN->binmode(":utf8") or die; while(<>) { s|\s+\n|\n|sg; print }'
   Wide character in print at -e line 1, <> line 1.
   包
