Special Characters in a Node Value

Question

Hi,
I have a node value which contains special characters (ex: it contains degree *°* between the text). When I am adding this text value to a node i am using the following code,
elementVariable.appendChild(documentObject.createTextNode("*node text value with different special characters*"));
How to handle these special characters, because when I open the generated XML file in Web Browser it is displaying an error when parsing this text value which contains the degree symbol.
Does anybody know how to handle this type of text values. If any one had links related to this, please send me.
Thank You.

Thanks for your reply DrClap. What you said regarding posting the query without understanding the code is correct. But I am not expert in XML and I didn't worked on it previously. I suddenly got the request to implement this in our application and i don't have time to learn, so i did some search and found the below code and used that in my program.
It worked for all the types of data, but it is failing only for the degree character (*°*). Could you please check the below code and tell me where I am doing wrong. I really appreciate your help.
