Actually that sounds like exactly the wrong way to fix the problem.

Instead, the Perl module should note the utf8 flag on the Perl scalar,
save it into memcached (which just stores bytes, and a bitmask of
client-defined flags), and then restore the utf8 flag on the way out.

For now, a workaround is to put all utf8 data into memcached as an

   $memc->set("foo", [ $utf8_string ]);

which will force to be used, which handles the utf8 flagging
and unflagging.
