Different results of UTF-8 encoding to URL parameter with particular languages between RawUrl and QueryString in HttpRequest

Update - 31 Aug

string test = "ö";
string unicode1 = HttpUtility.UrlEncode(test, Encoding.Unicode);
string unicode2 = HttpUtility.UrlEncodeUnicode(test);
Console.WriteLine("Result of unicode1: " + unicode1);
Console.WriteLine("Result of unicode2: " + unicode2);


we can see the different results. now the case is when i was using UrlEncode the parameter in URL for posting the data, it returns would become unicode2 when the browser is getting the resources.

it was strange that the value of the parameter "nm" in QueryString became different, its original string was "ööö", so we can see it in Url, after encoding by UTF-8, it became "%c3%b6%c3%b6%c3%b6%" in RawUrl, in normal case, it should keep the same result of encoding between RawUrl and QueryString. Does anyone know the reason?

I encountered an issue that the URL referrer will become to null after clicking the button.
I filled in the text "öööööööö", you can see the different encoding between c# and IE.

the url encoded by c#, it was captured by Fiddler

the url encoded by IE, it was displayed in IE status bar

Result of encoding by UTF8: “%c3%b6%c3%b6%c3%b6%c3%b6%c3%b6%c3%b6%c3%b6%c3%b6”

Result of encoding by IE: “%u00f6%u00f6%u00f6%u00f6%u00f6%u00f6%u00f6%u00f6”

does anyone know how it happen and give a hand?
