 Recently I encountered a problem with one of my posts where Wordpress
 failed to process some of the shortcodes. After hours of digging I found
 that one shortcode contains no-breaking space as separator between
 shortcode name and parameters.

 {{{
 [myshortcode\xc2\xa0param="...
 }}}

 Seems like somebody used external editor to edit post content and then
 pasted it into wp's editor.

 I used following quick fix to permit this problem in future :

 {{{
 add_filter( 'the_content', function( $text ) {
         return str_replace( "\xc2\xa0", " ", $text );
 }, 0, 1);
 }}}

 I think, it's not very good approach. Thus the question to core developers
 to fix this in shortcode parsing functions.
