Take a look at the -C argument for perl and the PERL_UNICODE environment
variable in http://perldoc.perl.org/perlrun.html
Examine the difference between
perl -E 'say "\x{df}"'
and
PERL_UNICODE=O perl -E 'say "\x{df}"'
That said, if you are working with the web, why in the world are you
sending UTF-8? HTML has entities for a reason. I would suggest using
HTML::Entities instead of trying to send non-ASCII characters through who
knows how many layers of things that can screw up UTF-8:
perl -MHTML::Entities -E 'say encode_entities "\x{df}"'
