need help in writing xml file into arabic language

Hi,

I'm facing problem while inserting Arabic data into XML File, ofcourse I'm 
unable to locate where the problem is, my application is as follows:

I have one XML file which contains all of my HTML text(my user interface), 
I am calling this XML file from the HTML file using JavaScript. in the 
browser it is displaying very good.
the prob.  is when I press Submit button by entering Arabic data as input, 
my C# program is extracting data from the XML Nodes and storing into the 
SQLServer database at the same time I am showing the saved data on the 
Browser it is displaying in question marks(like ???????)  in the browser as 
well as in the database.
(BUT IF I REMOVE THE USING OF XML AND DIRECTLY USING HTML AND C# IT IS 
WORKING VERY GOOD IT IS SHOW PURE ARABIC DATA, BUT HERE I HAVE TO USE XML 
AS A MIDDLE WARE)

how do I resolve this problem plz help me.
waiting for your quick response

Regards
Chait
