 As a consecuence of #10797, the patch to remove some characters like nbsp,
 ndash, mdash from slugs, existing posts that contained these characters
 are not longer accessible.

 This new code should only execute on every post/page save. However, when
 preparing the SQL query needed to find posts by slug, WP.org core uses the
 sanitize_title function, which assumes by default that we are saving the
 slug. Thus, if an existing post has "mymasscom%c2%a0class" as slug, then
 starting from that date these posts are not accesible because the searched
 slug is "mymasscom-class".
