As has been said in this thread (and elsewhere): To reproduce, use 5.012; or newer, or more explicitly: use feature 'unicode_strings';

I have the habit to always specify a minimum version I run in my programs, including demos for PerlMonks. I admit that it didn't occur to me that without a version declaration (or with a declaration of 5.010 or older) Perl behaves differently.
