Plugin Advanced Cart - Fehler nach Update auf 1.2.2

Habe eben in Shopware-Version 5.2.9 ein Update des Plugins Advanced Cart auf 1.2.2 gemacht. Leider erzeugt der Aufruf der Wishlist jetzt folgende Fehlermeldung:
Hat jemand eine Idee, wie ich das auf die schnelle lösen kann?

Die Fehlermeldung sagts eigentlich eh schon. Die Default-Einstellung der Mysql-DB war utf8_general_ci. 

Bei Plugins wo beim Erstellen neuer Tabllen nicht explizit die Kollation angegeben ist wurde dann in dem Fall utf8_general erzeugt. Bei JOINS über verschiedene Kollationen kommt´s dann zu dem obigen Problem. Habe nun die Tabellen und die Felder entsprechend auf utf8_unicode_ci umgestellt, dann gehts wieder
