get_the_content() and emojis

I have a post with an emoji in it. I want to be able to access it programmatically to convert it to HTML Entities. IE change ?? to & # 129380;

If you view text of the post you’ll see:
??

$contentString = apply_filters( ‘the_content’, get_the_content() );

I examine the $contentString and see ` but looking at the text after < code > tag in a text file I saved, it shows that something is hidden there. Probably an encoding issue.

How can I access the emoji after < code > tag and convert it to its HTML Entity?

I tried a regex search with unicode to no avail.

$pattern = '/< code >(\X+)<\\\/code>';
$result = preg_match($pattern, $contentString, $matches);

Thanks in advance!
