The answer to your question is here: http://www.question2answer.org/qa/28769?show=28769#q28769

In a recent commit a function was implemented to remove those characters from the core.

If you are not using MySQL 5.5.3+  or maybe you don't want to change your database structure you might also consider switching those characters to HTML before storing them. E.G.: 😁. A filter module should do the trick.

Thank you very much. That should do for me :)
Hi pupi, can you please tell me which function I have to modify in the core to use utf8mb4? (I have already changed the Database)
Check qa_remove_utf8mb4(). Just replace it with:

function qa_remove_utf8mb4($string)
    return $string;

I think that should be it (appealing to my memory!)
Thank you very much. That worked great (y)
