Incorrect string value: \'\\xC3\' for column \'description\' at row 1 in mySql

Here, In my table, I've one column name as description.

As per my error, I've tried many solutions from SO to change the collection type.

I've tried below collection

1) utf8mb4_unicode_ci
2) utf8_general_ci

Can anyone know what is the right collection for \'\\xC3\' this type of string?
