 I've found that non-breaking spaces ( ) can get converted to Capital
 A-circumflex (Â) in certain circumstances when creating and editing posts
 with Internet Explorer:

    1. When a non-breaking space is pasted to the Editor window and the
 post is saved.
    2. When a non-breaking space is typed into the HTML tab, the Editor tab
 is clicked, and the post is saved.
    3. When a non-breaking space is typed into the HTML tab, the post is
 saved, then the post is edited and saved.

 This can be a problem when the character is on a line by itself as
 Internet Explorer does not recognize the character when it's in the RSS
 feed and complains with the error:
 {{{
 An invalid character was found in text content.
 Line: 0 Character: 0
 }}}

 I think non-breaking space may be getting changed to &#160 and then this
 is interpreted as  (since it is "160" in extended ASCII).

 To workaround this problem I added the following line to the beginning of
 the TinyMCE_Engine.prototype.cleanupHTMLCode method in tiny_mce.js:
 {{{
 s = s.replace(new RegExp(' ', 'gi'), '');
 }}}
 Another thing that worked was changing the entity_encoding to "numeric" in
 tiny_mce_config.js . However this was less desirable as it will change all
 named entities to numeric, i.e., £.

 I verified the problem exists in the [http://mu.wordpress.org/latest.zip
 latest version] of TinyMCE included in WordPress MU (2.09). I briefly
 tried to see if I could reproduce the problem in the latest vanilla
 version of TinyMCE but could not reproduce the right environment since the
 version in WordPress MU is modified.
