Spanish accent characters are not displayed proper in excel file

Question

Hi
I have written a program which displays one report file (.xls file ) on the browser.
This report file is in spanish language and contains few accent characters like
("� � � � � � �"). These characters are not displyed properly in that excel file which is opened in the browser. I have used utf-8 encoding method. I tried with some other encoding methods available. But still this problem continues.
Kindly provide me help as soon as possible.
Thanks and
Regards,
Deval

File is generated through a java bean at runtime and it is not stored pgysically.
If I copy these characters from somewhere to new xls file then it will be displayed properly.
Sample code which is used for setting headers is as below:
     protected void setContentType (
          HttpServletResponse     p_response
     ,     InstanceData          p_instancedata
          p_response.setHeader ("Cache-Control", "no-cache");
          p_response.setHeader ("Cache-Control", "max-age=0");
          p_response.setHeader (
               "Content-Disposition", "inline; filename="
          +      p_instancedata.userId
          +      "_"
          +      System.currentTimeMillis ()
          +     ".csv"
          System.out.println("Content generator = ");
          p_response.setHeader("charset","utf-8");
          p_response.setContentType (EXCEL_CONTENT_TYPE);
For generating this xls file, format of data is XML. Means both request and response data will be in XML format.
Hope this information help in suggesting any solution for this problem.
