Setting the remote handle to utf8 makes perl automagically encode  
everything from a utf8 character string into a byte string (for you).

This isn't the engine's job.

It's the rendering pipeline's job to ensure that you have a document  
whos body is a string of bytes (rather than perl's internal characters).

Catalyst::Plugin::Unicode does this for you by calling uft8::encode  
(the perl internal character string is encoded into a byte string (in  
utf8)).

I can't see a crash at all here, that's shitty :/.
