Unicode string changes when Unicode data is submitted from Chrome to ASP.Net page

I have strange problem with chrome encoding. IE, FF and Chrome encoding is set to UTF-8. When I have a long Unicode string submitted the value received in the server side is totally distorted in Chrome but is OK with FF and IE.

The textarea has a string comprised of characters 768 to 800. The form is submitted. I want to get the same string on the server-side. Distortion of the string happens only in Chrome

Here is the Code

<form id="form1" runat=开发者_高级运维"server">
    <div>
    <textarea id="ta1" runat="server" rows="10" cols="50"></textarea>
    <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
</form>
<sccript>
    var ta1 = document.getElementById('ta1');
        var s = '';
        for (var i = 768; i < 800; i++)
        {
            s += String.fromCharCode(i);
        }
        ta1.value = s;
</script>
---------------------
Code behind
--------------------
protected void Button1_Click(object sender, EventArgs e)
{

string s = ta1.Value;
string s2 = "";
for(int i=0;i<s.length;i++)
{
   s2 += "i:" + Convert.ToInt32(s[i]) + "<br/>";
}

Response.Write(s2);

}

The output is 768 to 799 in IE and FF. But completely messed up in Chrome.

Please help.

There is an issue with the Chrome browser. Please add this, I hope your problem will be resolved.

Page.Form.Attributes.Add("enctype", "multipart/form-data");
