 As of r15929, sanitize_title in formatting.php calls remove_accents
 directly. remove_accents used to be called in sanitize_title_with_dashes,
 which in turn is one of the default filters applied in sanitize_title. The
 change takes away the possibility for plugins to change the title using a
 filter ''before'' accents are removed, or to avoid removing accents
 altogether.

 One of the plugins broken by the change is my

 Related tickets:
  * #9591, where the change originated
  * #15248, where unsalkorkmaz has a similar complaint that could at least
 have been worked around before the change, now there seems to be no chance
 to do so using the plugin API
  * #9492, where the deeper issue with WordPress indiscriminately removing
 diacritics (that's right, not all diacritics are mere accents,
 remove_accents is a misnomer) is addressed. With that I think one can live
 – as long as it remains possible to fix it via the plugin API.
