The utf8mb4 should be OK for the database. That is actually what I have but I changed to utf8… to verify it would work with the schema I provided.

I would like to know what the errors were you encountered when you imported the data. If it had to do with foreign key issues, you can turn off the foreign key check in import. If this allows your data to be loaded, you are no worse off than you are now but I expect you have number of orphaned records that should be resolved.
