Comment (by Jules Colle):

 I'm practically doing the same thing as @modernnerd. I'm copying code from
 the block editor to a HTML file, which I use later to dynamically insert
 pages in my testing/development environment.

 At some point, I'm creating the page from the HTML file like this:


 {{{
 $page_content = file_get_contents('/path/to/test-page.html');
 $page_id = wp_insert_post([
   //...
   'post_content' => $page_content,
 ]);
 }}}

 With this code I ran into the problem where the actual content on the page
 had `u003c/strongu003e` all over the place.

 Simply adding `addslashes($page_content)` seems to fix all these problems
 for me.

 Working code:
 {{{
 $page_content = file_get_contents('/path/to/test-page.html');
 $page_content = addslashes($page_content);
 $page_id = wp_insert_post([
   //...
   'post_content' => $page_content,
 ]);
 }}}
