Help with Displaying Chinese in Java from mySQL

From Eclipse Java, I run a PHP script which executes a stored procedure in a cloud mySQL database

mySQL Workbench can store and display Chinese characters correctly.

Eclipse returns the dataset correctly in English, but Chinese characters cannot be displayed properly.

This is what I 've tried so far:

(1) In mySQL, I created the table wikth this specification:
ENGINE=INNODB AUTO_INCREMENT= 3 CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

(2) In the PHP script, I specified the header like this:
header("Content-type:application/json; charset=UTF-8");

(3) The response is json_encoded, like this:
echo json_encode(array("db_response"=>$response));

(4) And in Eclipse, I've set thre preference to utf-8, like this:
Window -> Preferences -> General -> Workspace -> title file encoding Other UTF-8

Chinese (and other languages) characters are displayed like this on both Firefox and Eclipse-Java app
??????(??)????

All records in English are displayed correctly.

This is the setup I have in mySQL:
character_set_client utf8mb4
character_set_connection utf8mb4
character_set_database utf8mb4
character_set_filesystem binary
character_set_results utf8mb4
character_set_server latin1
character_set_system utf8
collation_connection utf8mb4_unicode_ci
collation_database utf8mb4_unicode_ci
collation_server latin1_swedish_ci

I do not know why the collation_server is set to "swedish"
I do not have a my.ini or my.cnf when I installed mySQL Workbench, so Icreated one myself.
