webrowser访问网页问题

Question

网址中含有中文参数，利用UTF8EncodeURI函数将中文转码为UTF8，将转好后的网址Navigate，

Dim myuri As Uri = New Uri("转好后的网址“）
webbrowser.Navigate(myuri)
访问完成后通过webbrowser.Url.OriginalString查询，网址又变成转码前的中文了，不知是为什么？怎么解决？

附：
Function UTF8EncodeURI(ByVal szInput) As String
Dim wch, uch, szRet
Dim x
Dim nAsc, nAsc2, nAsc3

    If szInput = "" Then
        UTF8EncodeURI = szInput
        Exit Function
    End If

    For x = 1 To Len(szInput)
        wch = Mid(szInput, x, 1)
        nAsc = AscW(wch)

        If nAsc < 0 Then nAsc = nAsc + 65536

        If (nAsc And &HFF80) = 0 Then
            szRet = szRet & wch
        Else
            If (nAsc And &HF000) = 0 Then
                uch = "%" & Hex(((nAsc \ 2 ^ 6)) Or &HC0) & Hex(nAsc And &H3F Or &H80)
                szRet = szRet & uch
            Else
                uch = "%" & Hex((nAsc \ 2 ^ 12) Or &HE0) & "%" & _
                Hex((nAsc \ 2 ^ 6) And &H3F Or &H80) & "%" & _
                Hex(nAsc And &H3F Or &H80)
                szRet = szRet & uch
            End If
        End If
    Next
    UTF8EncodeURI = szRet
    UTF8EncodeURI = UTF8EncodeURI.Replace("""", "%22")
End Function
