As the attachment did not appear to make it through, the actual SQL that
causes the 0 byte save is as follows:
DROP TABLE IF EXISTS bad_data;
CREATE TABLE bad_data ( id int NOT NULL, bad_data varchar(50) NOT NULL, PRIMARY KEY (id)
);
INSERT INTO bad_data (id, bad_data) VALUES(1, 'Dhabīḥah'),(2, 'ذَبِيْحَة');
Cheers,
