IE上的Web API编码错误

Question

Why I get this symbol � instead of ąčęėįš. I pass parameter via Ajax. On chrome works fine, but on IE its not working.

Ajax:

var comment = document.getElementById("commentstext").value;
$.ajax({
    type: "get",
    dataType: "json",
    contentType: 'charset=utf-8',
    url: url,
    data: "state=false&comment=" + comment
});

api:

[DnnAuthorize()]
[HttpGet]
[ActionName("insert")]

public void InsertRecord(bool state, string comment)
{
       ...
}

url: http://.../API/Rate/insert?state=false&comment=ąčęąčę

IE version: 11 and 9

Chrome version: 33 and 46

Now I cann't test other browser

Its work after i add this: comment = encodeURIComponent(comment);

How about this:

var comment = document.getElementById("commentstext").value;
$.ajax({
    type: "get",
    dataType: "json",
    url: url,
    data: { 
        state: false,
        comment: comment
    }
);

And also specifying UTF encoding in your web.config:

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