 For testing:

 1. Manually insert this into a post_name in the database:

 {{{
 foo-%c3%a5-bar-%e2%80%9cquoted-text%e2%80%9d
 }}}

 The first char is "å", and the ones around "quoted-text" are curly quotes
 from Microsoft Word. This was the original source:

 {{{
 foo å bar “quoted text”
 }}}

 2. Once you have that in a post_name, open that post for editing. First
 thing to do is hit Update without making any changes. The permalink slug
 should stay the same. Verify the post is still accessible.

 3. Click "Edit" next to the slug and then immediately press "OK" without
 making any changes. The slug stay the same. Try another Update to verify.

 4. Next, manually edit the slug, and append something (like "-appended").
 On pressing OK, you should get a new, fully sanitized, like "foo-a-bar-
 quoted-text-appened". Save and verify. Make sure the 301 works from the
 old URL.

 5. Try creating a new post or page with a title of {{{foo å bar “quoted
 text”}}}. Make sure you get the newest sanitization when publishing.
