CKEditor requires JavaScript to run. In a browser with no JavaScript support, like yours, you should still see the contents (HTML data) and you should be able to edit it normally, without a rich editor interface.
In this sample the editor is configured to edit entire HTML pages, from the <html> tag to </html>.
