Question

My problem is not too hard but really annoying.

I’m sending values to Generic Handler via Ajax like that way.

xmlHttpReq.open("GET", "AddMessage.ashx?" + (new Date().getTime()) +"&Message=" + Message,true);

when message contains İ,ç,ö,ğ,ü,ı they are looking like that on Handler �������
In context.Request.RawURL İ,ç,ö,ğ,ü,ı these characters are looking as it should. But in context.Request.Url they are looking like ������� and when i want QueryString values it gives me ������� what can i do?

A couple of things to check:

1. In web.config you’ve set UTF-8:

   <system.web>
       <globalization requestEncoding="utf-8" responseEncoding="utf-8" />
       ...
   </system.web>
   

2. You’ve a proper meta tag in your HTML page:

   <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
   

3. All your .aspx, .ascx, .master, .ashx,… files are saved as UTF-8 with BOM on the hard drive.

4. You are properly URL encoding parameters before sending them (using the encodeURIComponent method):

   xmlHttpReq.open(
       "GET", 
       "AddMessage.ashx?" + 
           (new Date().getTime()) + 
           "&Message=" + encodeURIComponent(Message),
       true
   );
