It is here http://scsys.co.uk:8001/36569 and it shows (using option -u),
that FCGI indeed encodes all data as soon as the utf-8 flag is on.
This is very interesting, because the latest FCGI release is nearly
seven years old. Did the utf-8 flag exist at that time at all?
Is there something in Perl's guts that does such encoding automatically?

I know hardly anything about Perl XS code. Maybe someone with a clue
could have a look at FCGI.xs^H^HXL?
As a quick fix, we could utf8::downgrade($buffer) in
Catalyst::Engine::FastCGI right before syswrite. Doesn't hurt, as far as
