I was faced with this problem this morning and it annoyed me a lot until I found this solution:

Stream stream = new MemoryStream(System.Text.Encoding.Default.GetBytes(Content_Of_HTML_File_In_String)));
webBrowser.NavigateToStream(stream);

Compared to the solution above, you wont expect any "COMException" or something of this sort.

I have solved it with the following:

    static void webBrowser_LoadCompleted(object sender, System.Windows.Navigation.NavigationEventArgs e) {
        var webBrowser = sender as WebBrowser;
        if(webBrowser == null) {
            return;
        }
        var doc = (IHTMLDocument2)webBrowser.Document;           

        doc.charset = "utf-8";
        webBrowser.Refresh();
    }

This is very quirky.

  1. My solution was to put an explicit meta tag in my HTML file - "My Page.html"

    <meta http-equiv='Content-Type' content='text/html;charset=UTF-8'>

  2. Then using the standard Web Browser .NET control I then created a URI object first.

    webBrowser1.Url = new Uri("My Page.html");

  3. Then draw the page using the refresh method.

    webBrowser1.Refresh();

Note if you use the Navigate method directly it fails to pick up the utf-8 directive, but the URI and refresh approach does.

Quirky, but it works.

The WebBrowser control uses Internet Explorer internally, whichever version you have on your local PC. If you can fix the problem in IE, it should be fixed in the WebBrowser control.
