And I’m creating a script to read those data and insert into my database.
I’m using Django using MariaDB as my database and I found this error while inserting to the database.

django.db.utils.OperationalError: (1267, "Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='")

After several minutes find a solution, the issue occurs because python using unicode string but my database doesn’t.

To fix this issue, I just need to update my database table collation in shell following below.

ALTER TABLE my_table_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
