Solution for languages that render as entities

[Ampersand]

By default, the editor converts special characters like umlauts (üäö …) to their HTML-equivalents. This is not needed anymore if you encode your pages in UTF-8. So you can set this option to false.

This refers only to WYSIWYG editor namely CKeditor.

I switched this editor off and still have entities like the famous &oacute. I even hacked basic.php according to the above, and still get have entities in page content. HTML <title>s hower render without entities (as of 3.0).
