 Hello there. I have found a problem in some characters when changing from
 HTML to Visual.

 If you use `&darr;` in HTML view to have a down arrow, when you change to
 Visual you can see the down arrow. It's not interpreted, it is replaced
 for the `↓` character. When you hit publish, the ↓ transforms into `?`.
 Same problem if I use the `special chars` button in Visual view. They
 transform into `?`.

 It happens for all the ASCII special characters. Here is a list of the
 working/not working special characters  in UTF-8.

 Doesn't work (changes into ?)

 {{{
 &prime;
 &le;
 &infin;
 &clubs;
 &diams;
 &hearts;
 &spades;
 &harr;
 &larr;
 &uarr;
 &rarr;
 &darr;
 &Prime;
 &ge;
 &prop;
 &part;
 &ne;
 &equiv;
 &ape;
 &ap;
 }}}

 Works (shows correctly):

 {{{
 &fnof;     ƒ
 &bull;       •
 &hellip;  …
 }}}

 I have tested it using WordPress 3.4-alpha-19719 & Twenty Eleven & UTF-8
