Comment (by nilovelez):

 I have just updating a working patch.

 I have applied the `remove_accents()` function to the
 `sanitize_file_name()` in `/wp-includes/formatting.php` just after
 `$special_chars` are removed.

 **Test filename:** Bolígrafo Ecológico 2€.jpg
 **Before patch:** Bolígrafo Ecológico 2€.jpg
 (Bol%C3%ADgrafo%20Ecol%C3%B3gico%202%E2%82%AC.jpg)
 **After patch:** Boligrafo-Ecologico-2E.jpg
