I have an HTML file with a ® (copyright) and ™ (trademark) symbol in the text. These are just two among many other symbols. When I read the html file into a literal control it converts the symbols to something else.

The copyright symbol converts to ? (open box in ff) The trademark symbol converts to ™ (as expected)

If (System.IO.File.Exists(FullName)) Then
   Dim StreamReader1 As New System.IO.StreamReader(FullName)
   Contents.Text = StreamReader1.ReadToEnd()
   StreamReader1.Close()
End If

Contents is a <asp:Literal runat="server" ID="Contents"></asp:Literal> and it's the only control in the aspx page.

From some research I think this is related to the encoding but I don't know why it would change how to fix it.

The html file does not contain any Content-Type settings in the head section.
