Comment (by oekarlsson):

 I have tried this patch on IIS8.5, PHP 7.01 and a multisite WordPress
 installation. It doesn't work as expected. The sanitize_file_name function
 that receives the reencoded filename from this code returns an empty
 string. I can make it all work if I comment out this line from the
 sanitize_file_name function:

 $filename = preg_replace( "#\x{00a0}#siu", ' ', $filename );

 But that is not a practical solution...
