 When you call wp_check_invalid_utf8() with 2nd param set to true, it tries
 to strip invalid utf-8. Now it removes 1st invalid utf-8 char and all
 chars after it, no matter if they are correct or not. Additionally it can
 print following notice:

 Notice: iconv() [function.iconv]: Detected an illegal character in input
 string in .../wp-includes/formatting.php on line 437

 Attached patch changes this, so function removes invalid chars only.
 Additionally it is less configuration-dependent, because it can use either
 mb_convert_encoding() or iconv().
