Your issue is not with Petal, but with Perl in general. $Template->process() 
gives you a Perl Unicode character string. It's your responsibility to encode 
it according to your needs (that would be UTF-8) on output. Simply doing a 
print in your test script will encode the character string to the platform 
encoding (usually latin-1).

Same would  happen if you just printed some constant Unicode string:
perl -E 'use utf8; say "ödögödöckö";'

To get UTF-8 output, you could use binmode:
perl -E 'use utf8; binmode STDOUT, ":utf8"; say "ödögödöckö";'

Have a look at https://metacpan.org/module/perluniintro for further 
information about how to use Unicode in Perl. And remember: debugging 
character encoding problems _sucks_ because everything has been processed by 
multiple programs before reaching your eye (for example by your program, Perl, 
your shell, your terminal, ...). Always make sure that you know exactly how 
your data looks like every step of the way. If in doubt, use hexdump.

Regards,
Stefan
