I don't think it is locale related, I've used both "en_US.utf8" and
"en_US.UTF-8" in the past without issues.
And encoding names are used in many other places.

My guess is that you have somewhere a XML file with a wrong declaration

    <?xml version="1.0" encoding="UTF8"?>

where the proper declaration would be:

    <?xml version="1.0" encoding="UTF-8"?>

There are some configuration files both in /etc and $HOME that are
read upon initialization of Gtk and Qt (see /etc/fonts/*), so I'd
check those first:

    $ grep -ir 'encoding="utf8' /etc
    $ grep -ir 'encoding="utf8' ~/.config
