How can I go about stripping non-ASCII characters from permalinks?

I’m trying to create a plugin to not allow any weird characters into the permalink such as ?, ?, ?, ∞, &, etc…

I did a filter onto the ‘editable_slug’ and while this works for display purposes (the weird characters get filtered out), even though it might not show up in display, it is still being passed through when I update a post.

Anyone know how to actually make sure the data is passed AFTER I have cleaned it up? Or any idea on how I would go about doing this? Thank you!

Here is my plugin for reference:

if( !function_exists( 'strip_weird_permalink' ) )
{
	function strip_weird_permalink($post_id)
	{
		$output = $post_id;
		// strips all *non-ascii* characters
    		$output = preg_replace('/[^(\x20-\x7F)]*/','', $output);
    		return $output;
	}
	add_filter('editable_slug', 'strip_weird_permalink', 10, 1);
}
