save plain text file

How can I create a text file that is not in a UTF format and is just plain text?

This is the code I have but it creates the text in UTF8

Private Sub PlacefileUpdate_Tick(sender As Object, e As EventArgs) Handles PlacefileUpdate.Tick
        Dim FILE_NAME As String = "X:\Data\polygon_placefile.txt"

        My.Computer.FileSystem.WriteAllText(FILE_NAME, "", False)

        If Verticies.Items.Count = 8 Then
            Dim i As Integer
            Dim aryText(14) As String

            aryText(0) = "Title: Polygon"
            aryText(1) = "Threshold: 999"
            aryText(2) = "RefreshSeconds: 1"
            aryText(3) = ""
            aryText(4) = "Color: 255 255 255"
            aryText(5) = "Line: 3, 0, Polygon"
            aryText(6) = Verticies.Items(0)
            aryText(7) = Verticies.Items(1)
            aryText(8) = Verticies.Items(2)
            aryText(9) = Verticies.Items(3)
            aryText(10) = Verticies.Items(4)
            aryText(11) = Verticies.Items(5)
            aryText(12) = Verticies.Items(6)
            aryText(13) = Verticies.Items(7)
            aryText(14) = "End:"

            Dim objWriter As New System.IO.StreamWriter(FILE_NAME, True)

            For i = 0 To 14
                objWriter.WriteLine(aryText(i))
            Next
            objWriter.Close()
              End If
    End Sub
