wp_mail encode ’ in ’ in subject

It’s look OK with : html_entity_decode

wp_mail("[email protected]","new article : ".html_entity_decode($get_title),"The message is OK with é è à",$headers);

Not so good, another try :

wp_mail("[email protected]","new article : ".$post->post_title,"The message is OK with é è à",$headers);
