The web page I want to include is in Icelandic but no international characters show up in the included html in my page.
The Include uses standard HTTP requests, so it does not use any special international transformations.
Please try to use Unicode for your pages:
1. Put the <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> instruction into the <HEAD> section of your aspx page.
2. Add the encoding values to the aspx page directive:
<%@ Page ResponseEncoding="utf-8" RequestEncoding="utf-8" %>
3. Use instructions in your Web.config file:
<globalization requestEncoding="utf-8" responseEncoding="utf-8" />
