The language string $lang[PEDIT_DELETE] appears in 3 language files, editpost.php, modifypost.php and previewedit.php. It looks like one of the words in their might be considered a special character, meaning it won't translate properly in HTML. It's possible if you change this to another word that means the same thing it could resolve it. If it does, I'd appreciate to know what you changed it to so I can make the change in the main distribution.
