Jersey web service non-ascii characters - rest

Question

I am new to REST and jersey. I wrote a simple RESTful Web Service using Jersey 1.17 API. The Web service accepts data through POST method. When I pass data having non-ascii characters, it does not read them correctly.
#POST
#Path("hello")
#Consumes(MediaType.APPLICATION_FORM_URLENCODED + ";charset=UTF-8")
public Response hello(#FormParam("message") String message) {
System.out.println(message);
return Response.status(200).entity("hello" + message).build();
}
When I pass data having non-ascii characters in parameter 'message' it does not print it correctly.
curl --data "message=A função, Ãugent" http://localhost:8080/search/hello/
POST method prints "A fun??o, ?ugent"

I do not think Jersey is caring about the charset that is defined at #Consumes. I guess Jersey simply uses the request.getParameter method that uses the encoding of the request to resolve parameters.
You have many options to set the encoding:
In case the servlet container supports, set the default encoding of the connector
Set the default encoding of the jvm to UTF8
Create a Servlet Filter that catches this call and call request.setCharacterEncoding("UTF8"); In this case you must ensure that setCharacterEncoding is called before any other getter function (like getParameter) as the character encoding is set during the first get call on the request.
Do a transform on the parameter value by hand. You can get the ServletRequest and query the encoding. After that you can say:
new String(message.getBytes(currentEncoding), "UTF8");
In your case I would prefer the third one.
