Errors restoring database. utf8mb4 & utf8 (no replies)

Hi there guys, I am running WAMP server 3.0.4 32 bit on Windows 10 x64 (Apache 2.4.18 mysql 5.7.11 php 7.0.4) as a development platform with Wordpress. Periodically a backup is made out of the WAMP local install and a restore is performed onto the live server with no problems at all.

After a while I have discovered that the live server has a server connection collation set to utf8_general_ci, while WAMP's is set to utf8mb4_unicode_ci. Also I have discovered the Wordpress database contains tables with mixed collations and charset (utf8 & utf8mb4).

Yesterday after months of usage I have attempted to restore locally on WAMP a backup made from the live server, however the restore partially failed with a lot of errors.

What is preventing the restore?

I have also added the following to my.ini

[wampmysqld]
max_allowed_packet = 256M
sql_mode=IGNORE_SPACE,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION


This is an error example:
