Seems like this happens when you use binary collation, at least the same happened to me. To convert the bytearrays to Unicode strings, you can add a custom converter class:

class MyConverter(mysql.connector.conversion.MySQLConverter):

    def row_to_python(self, row, fields):
        row = super(MyConverter, self).row_to_python(row, fields)

        def to_unicode(col):
            if isinstance(col, bytearray):
                return col.decode('utf-8')
            return col

        return[to_unicode(col) for col in row]

sql = mysql.connector.connect(converter_class=MyConverter, host=...)
