Random NBSP's / Child Theme / add_filter

For some reason there appear random non-breaking spaces on our site: openstack.hosting, what’s even weirder is that these are not being rendered properly causing the words separated by the nbsp to stick together.

After quite some searching I found that this is probably a TinyMCE issue for which I found the following solution: https://ckmacleod.com/2017/03/23/exterminating-non-breaking-space-bug/

So I created a Child Theme for Enfold using http://kriesi.at/documentation/enfold/using-a-child-theme/, I’ve imported all the settings and all is good in the world. Except for those pesky nbsp’s that are still appearing randomly in my content ;)

However, when I edit my Child Theme’s function.php and add the following code it literally does nothing when I save content using the Avia editor:

/* remove all nbsp's when content is saved */
add_filter('content_save_pre','remove_buggy_nbsps',99, 1);

function remove_buggy_nbsps($content) {
   //strip both types of non-breaking space in case NGG or similar is installed
   $content = str_replace(' ',' ',$content); 
   $content = str_replace('\xc2\xa0',' ',$content); 

   return $content;
}

I’ve added some debug code to this custom function and by the looks of it, it is simply never called. So I suspect I need to find another hook to filter the content as soon as it is saved from the Avia editor.

Does anyone have an idea how to add a filter to my child theme’s functions that will sanitize page content once I update or add it?
