There are 900 paths in the googles index to our homepage containing illegal characters. Example:
Note the character "%4N".
I have no idea where they come from, but would like to update google index with a correct URL using "canonical" in the html code.
But the problem is our apache2 server immediately sends a 400 error if you click the link above. How can I configure apache2 not to give an error code, but instead treat the link above as "correct"? Maybe replacing the char %4N with nothing.
