Internationalization support for Jquery UIs

Internationalization support for Jquery UIs

Hi,
I am using Jquery for UIs in my application. We are now adding internationalization support in the application. When we are sending portuguese characters in the AJAX response, Browser is not able to show these characters. Below are the things which we have tried:
 

1)      Updated  value of dataType inside ajax function like html, text, xml etc.

 

2)      Content type updation inside ajax function :-- Used Utf-8, ISO-8859-1 etc

 

3)      Different encoding options inside ajax function :-- Tried to change the encoding where we are printing values of drop-down

 

4)      Tried with changing jquery code by adding browser specific code (as IE support ActiveXObject in older versions, but Mozila, Chrome etc. support XMLHttpRequest)
 
 
Nothing seems to be working. Any help would be appreciated.
 
thanks..
