Problems with & nbsp; in XHTML+RDFa 1.1

[eluser]Razican[/eluser]
I tried to extend the profiler, but with no result since I needed to change the run() function, but it would not find the compilers, as they are protected.. Now I have extended the output class, in application/core/My_Output.php and it works, It will even change other nbsp inserted by other parts of the system.
