Comment (by mdawaffe):

 I worry about `mb_detect_encoding()` but don't have any data or experience
 to validate or assuage that worry.

 I know we're using this code on WordPress.com in places.  In other places,
 we use code that explicitly converts from the `blog_charset` (no attempt
 at auto-detection) to UTF-8.
