Go to WP Seo Settings and change title seperator from – to anything else.
This worked in my case. WP seo replaced <!– to <!- and formating didn’t work.

@joost de valk no this is enough for fixing the display in the admin grid, it would be great if you add the js modification for the metabox display

@francesco1119 let us know if you find any problem. Offer the beer to plugin author he deserves it more than me, thanks anyway

No problem I would try to give bigger priority to the filters. Give a try and let us know.

perqa this is correct. Only wp-seo-metabox.js will be ovewritten if you update the plugin. I will contact with him to see if he could incorporate the needed js modifications.
There will be not problem with functions.php as long as the plugin author does not change the filters (I do not find any reason to do so).

I created a modified version of the wp-seo-metabox.js give a look if you want.

Τhe Snippet Preview uses javascript for the parsing of the title and description. So the shortcode is not taken into account, this needs modification of the plugin core wp-seo-metabox.js file.

KOKON in the admin part the metabox uses JavaScript for the title parsing but in my theme it works ok

Guys try this in your functions.php with the latest version of WordPress SEO

// Enable qTranslate for WordPress SEO
	function qtranslate_filter($text){
		return __($text);
	}
	add_filter('wpseo_title', 'qtranslate_filter', 10, 1);
	add_filter('wpseo_metadesc', 'qtranslate_filter', 10, 1);
	add_filter('wpseo_metakey', 'qtranslate_filter', 10, 1);
