hi @bdubb, welcome to Trac and thank you for your concern. Unfortunately, it is not possible for me to reproduce the problem described, e.g. via the Playground. Please make sure that your problem occurs in a pure WordPress without any plugins and with standard themes. If so, describe in more detail how you can reproduce it.

If you need general support, please contact the support forum: ​​https://wordpress.org/support/forums/

Could you check for wp-includes/utf8.php in the html directory? That new file might have failed to install properly there.

Here's what happened:

Update failed to update wp-settings.php in root. Which contained the require for utf8.php.

Manual update and I'm back in business. Sorry for the confusion. Thx for the thoughtful responses.

Glad to hear it is now working and thanks for following up @bdubb! I'm closing this as invalid which is the unfriendly term used to say it was resolved in a way that didn't find an issue in the Core WordPress software.
