 My client used Unicode Chars (Icons) in the URL. WordPress doesnt seam to
 filter them.

 So they where saved. Emediatly after, the page didnt work anymore. Even
 back in draft, the page delivered a white page and not the page content.
 I did remove the icons. But page was still broken.

 Needed to move page content in a "new" page and save it to reenable it
 again. Added icons to the URL and the same issue again.

 Why are Unicode Icons not filtered from the URL? Can you please apply a
 filterin mechanism for only valid char in the url? Icons are not supposed
 to be in the url I think.
