Why are Greek characters encoded like “α”? I can’t search for them in my browser

The WYSIWYG editor automatically encodes Greek characters to entities in the "text" mode. They can be stored in pure, non-encoded format only in the "Source" mode of the editor.

You can change this by turning this encoding off in the editor configuration:

Please find the ~\CMSAdminControls\FCKeditor\fckconfig.js file

and approx. in the line 79, please change the following property value from "true" to "false":

FCKConfig.IncludeGreekEntities = false;

Please note that you may need to clear the cache (temporary files) of the browser to apply the changes.
