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 Placeholder plugin is available. It replaces text in the format of [[text]] to uneditable sections, and lets the user edit them and create new ones using a dialog.
[[text]]
With default configuration: <p>This is a [[sample placeholder]]. You are using <a href="http://ckeditor.com/">CKEditor</a>. </p>
