Fixing UTF encoding in AJAX requests on Internet Explorer

The legendary status of Internet Explorer for being special among all browsers was reminded to me when I discovered that sending a variable with non-latin character in a GET request over AJAX is apparently too troubling for IE. The result is that characters in greek are either transformed to latin ones or just disappear. This was all in a simple call like this:


(Where [i]what[/i] was the value of an input used in a AJAX-powered “quick search” form. Calling the same URL on a normal (non-AJAX) request everything worked perfectly.
The solution (after trying for hours to figure out what kind of transformation IE was doing on the value of the string), was simple enough: send it via POST

$.post("/ajaxsearch/&id=$id&",{ f: what }, 
 function(returned_data) {

I guess since it was a input box, I should have treated the call as a form and used POST from the start, right?
