javascript - Losing unicode Char when sending via query string in an AJAX call -

I am trying to send some data to Ajax call to update a record in the server

< Pre> var ordernotes = $ .ajax ({url: 'ajax action / order notes update.aspx? Orderdid =' orderdid + 'and notes =' + $ ('# text notes'). Val (), async : Footy}) .responseText;

"Notes" are in Unicode.

When I'm checking the QuickString on the receiving page, I can not find the same code (Text not entered I'v).

Does anyone know anything about it? Is this data from the asp.net textbox? What can I do about it?

ps is like everything else before sending me, just everything is going wrong in the query string ... 10x

  jQuery.ajax ({url: 'Ajax actions / order notes updated. Espx', data: {order id: order id, notes: $ ('# txtNotes') .val ()}, Async: wrong, type: 'go', success: function (data) {// do something here}})
