I've solved in page templates code:

             if not response.headers.has_key('content-type'):
                 response.setHeader('content-type', self.content_type + 
';charset='  + self.output_encoding) <- here add the utf-8, the 
publisher will find this filled and avoid to put the default.

Is there a better way? Thanks!
