Thanks for the quick reply. I tried that, too, and while the regexp then works, the behavior changes.

With only 'use utf8': 
% ./test.pl
yep, is UTF8
success with B?ck

I see, "use encoding" also sets binmode on STDIN and STDOUT, so that while just using 'use' I need to explicitly add the binmode.

With use utf8 plus "binmode STDOUT ':utf8'": 

% ./test.pl
yep, is UTF8
success with Böck

(My, Perl's unicode handling is complicated.) Now to see if I can apply this learning successfully to the original application, which is far more complex...
