[TRINIDAD 1.0.11] Why XmlHttpServletRequest is forcing encoding to 'UTF-8'??

[Rafa Pérez]

Hi all,

we are using Trinidad 1.0.11. Our application uses data and jsps encoded in ISO-8859-15 for some reasons and we have tried to force this encoding on all the requests. However, I have noticed that XmlHttpServletRequest on trinidad-impl.jar forces all PPR requests to be encoded in 'UTF-8'. Is there any particular reason for this not to be configurable?
We have a commandButton with partialSubmit="true" and when it is clicked, the PPR request generated transports all the values in the tr:form encoded in UTF-8. Makes this sense? I thought that when a PPR event is generated by clicking a commandButton, no values of the form where processed. Am I wrong?

Regards,
