Older versions of MySQL don't support utf8mb4 properly.
Which is why we were asking if anyone knows how to export or alter the database to go from utf8mb4 back to utf8.
If you're going to be importing into an older version of MySQL, then you need to develop on that same older version of MySQL. Downgrade your local dev version if you need to do this sort of thing.
That's good to know going forward but doesn't help with our current situation unfortunately.
