Description

I got the following error message notice when a post comment included the ‘’ special character.
When I approved the comment, there was no further error message generated.
I have not seen this message before – but then again, we rarely get special character in comments.
I am using WordPress 5.1.1. The WP-config: ‘define(‘DB_CHARSET’, ‘utf8′);’
Can someone please advise how to fix this?

Regards and thanks,
Angus

Hi @HisKingdomProphecy, welcome to WordPress Trac!

Thanks for the ticket, I was able to reproduce the issue.

Sorry for asking this question when @SergeyBiryukov already reproduced the issue.

I may have done it wrong way, but when I posted this comment Jesus ❤ you, it got saved without any error notification and displayed perfectly. Also when I edited and saved the comment I didn't get into any issue either. It is still displaying correctly after edit.

I also have define( 'DB_CHARSET', 'utf8' ); set in my wp-config.php.

Would you mind placing the exact steps here to reproduce?

I'm pretty sure @subrataemfluence is onto the root. Heart emoji is not under the utf8 Charest in MySQL, and requires ut8mb4.
