Escape and enclose by same symbol doesn't work - mysql

Question

I have a table with a nullable column:
CREATE TABLE test (id INT, value INT);
INSERT INTO test VALUES (1, null);
I export it to csv using
SELECT * FROM test
INTO OUTFILE '/tmp/test.csv'
CHARACTER SET 'utf8'
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '"'
The output file looks like this:
1,"N
Then I try to import it:
LOAD DATA LOCAL INFILE '/tmp/test.csv'
INTO TABLE `test`.`test`
CHARACTER SET 'utf8'
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '"';
Query OK, 1 row affected, 1 warning (0.01 sec)
Records: 1 Deleted: 0 Skipped: 0 Warnings: 1
And it does't work and generates the following warning:
SHOW WARNINGS;
Warning 1366: Incorrect integer value: '"N' for column 'value' at row 1
And it doesn't insert this row. For some reason escaping doesn't work for this case. It does work if field are escaped and enclosed by different symbols.
But I can't use different symbols because I can't change export query because I use Google Cloud SQL and export to csv can be done only from google web console without ability to edit the query.
I've seen multiple examples on the internet that double quote in both cases should work. Am I doing something wrong?
