Upgrade to Apache 2.4 breaks encoding in a PerlOutputFilterHandler

Hi list,

My application has the following general configuration, which works fine with 2.2 : a perl script generates the 'core' html content for a given location, and a filter adds some additional generic content. The basic Apache configuration directives are :
 
 <Location /base/agenda_general>

  SetHandler perl-script

   Marica::Base::Agenda::agenda_general

 </location>

 <LocationMatch \/base\/>

  PerlOutputFilterHandler Marica::Base::Filter::html_head_and_tail

 </LocationMatch>

When I upgrade to Apache 2.4, this happens :

The filter appears to get the encoding wrong when processing the content of the PerlResponseHandler (the garbled part on the right), while the part that it adds (the menu on the left) is displayed correctly.

Code for the PerlOutputFilterHandler is here :

Code for the PerlResponseHandler is here :

Any idea of what might cause this?
