Comment (by Otto42):

 In the Visual editor, if you insert more than one space in a row,
 presumably in an attempt to space something out vertically, the Visual
 editor will make every other character a non-breaking space (A0). This
 prevents that vertical space from collapsing back to a single space when
 you switch between Text mode and Visual mode. It also prevents the HTML
 rendering of the data from collapsing the extra space as well.

 This appears to be intentional and part of TinyMCE, which means we should
 probably recognize A0's for shortcodes as well.
