It seems that internet explorer doesn't behave the same way as firefox.
So test with both browsers.
Maybe the default encoding of the system has also something to do with it.
Anyway changing the httpheader should fix this problem

Below are to traces of HTTP messages passing along that show the issue.
You can see that in both cases the server is replying with the same charset on the content-type.

Checking fast on the code it shows that the encoding to use is not passed as a parameter to the serializer, but injected in the XML stream. This makes the info however only available at the time the sax-events are passing through the pipe, apparently this is too late for the content-type to be changed....
