I`m trying to use google`s unofficial weather API,,
You can find it here
http://www.google.com/ig/api?weather=amman[^]

i use the doc.load(urlgoeshere) function and its working fine..
but when i add a query to he api`s url (to request an arabic langauge response)
(http://www.google.com/ig/api?weather=amman&hl=ar[^] )
the doc.load function wont load and gives the following error msg

"System.Xml.XmlException: Invalid character in the given encoding"

i think the (&) in the url is what causes the error.. any help would be appreciated.

You probably need to use the encoding of the xml file returned by the weather API. Have a look at the link:

Good luck!

The exception happens later on, when the response from Google is to be loaded by the XmlDocument. And Google uses a different encoding for the English and Arabic response, resp.: ISO 8859-1 for English, and Windows-1256 for Arabic.
Following code works on my computer with both requests:

C#

XmlDocument doc = new XmlDocument();
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com/ig/api?weather=amman&hl=ar");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();
System.IO.StreamReader reader = new System.IO.StreamReader(resStream);
doc.Load(reader);
