3 Slashes appear after Apostrophe in custom fields after updating product-site

I think you should use more appropiate value in the custom field and output it within HTML when needed; for example the productheadline value could be only “Desktopia Pro”, which is a more real head line, I can not imagine a headline value containing HTML markup, then you can output it within a HTML markup like this:

<div style="margin-bottom: 20px;">
  <h1><?php echo get_post_meta( $postid, 'productheadline', true ); ?></h1>
</div>

I really think that this approach is much better and future proof. For example, using HTML markup in a custom field makes the custom field data unexportable and not reusable. For example, what happens if you need a different HTML markup in the future? You will have to edit every single custom field. Not very good. What if you need to access the product headline to be used elsewhere (feeds, REST API, etc)? You will get a HTML markup instead of the real headling; not very good.
