Passing non-English parameters to reporting services via URL access

Few weeks ago I faced a problem when I was using SQL Server Reporting Services to generate a report in which all parameters' values in Arabic.

The problem appeared when I used this report through URL access, and passed the parameters' values throug URL. I did a simple report to reproduce the problem. Let's say I have a report like this

http://schemas.microsoft.com/sqlserver/reporting/2003/10/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
  0.25cm
  2.5cm
 
   
     
       
        textbox1
        0.63492cm
        6.75cm
        0.25cm
        true
        =Parameters!CustomerName.Value
        1.5cm
     
   
   
  2.5cm
  16cm
  2.5cm
  true
  29.7cm
  true
  21cm
  573728dc-7d8a-4652-8a69-3a9c1a55887b
  2.5cm
 
   
      String
      true
      CustomerName
   
 
  en-US
When you call this report through URL access and pass the parameter CustomerName like this&rs:Command=Render&rc:parameters=false&CustomerName=???You note that the report doesn't recognize the parameter value passed. The report considers it as empty string.  To avoid this I found in Service Pack 2 documentation that you need to add this parameter rs:ParameterLanguage= so in my case I should add rs:ParameterLanguage=ar-EGI tried this but It didn't solve the problem. I tried another way and it solved my case, I URL encoded my parameters values before passing them to the report.If you are using web application and you want to show a report. You can use Server.URLEncode("").If you are using windows application, you need to reference System.Web.dll assembly and use HttpUtility.UrlEncode(" (it's static/shared method).I hope this help who may face the same probelm.http://blogs.msdn.com/mohamed_sharafs_blog/
