I have a php script that copies data from 1 table to another.The source table and its fields are utf8mb4_general_ci while the target table and its fields are utf8mb4_unicode_ci.
I get an "Incorrect string value" each time the script tries to insert a special characte like "è".
The DataBase version is 8.0.36-28. The script used to wok well with 5.6.51-91.0-log DB version.I tryed with and without mb_convert_encoding, the result is the same.
