Para solucionarlos agregar estos parámetros en el archivo de configuración de mysql my.cnf:

[mysqld]
…
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
skip-character-set-client-handshake

[client]
default-character-set = utf8mb4

[mysql]
default-character-set=utf8mb4

Comprobación:
Abrir una nueva sesión en mysql y verificar que la codificación de caracteres esta correcta:
