THE SITUATION:
Sorry in advance if this question has already been asked, but the solutions aren't working for me.
No matter what I try, I cannot store emoji in my database. They are saved as ????.
The only emojis that are properly saved are the ones that require only 3 bytes, like the shy face or the sun.
The actual utf8mb4 is not working.
It has been tested on both Android and Ios. With same results.
VERSIONS:
Mysql: 5.5.49
CodeIgniter: 3.0.0
THE STEPS:
I have modified database character set and collation properties.
ALTER DATABASE my_database CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ciI have modified table character set and collation properties.
ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ciI have set each field of the table, where possible, as Encoding:
UTF-8(ut8mb4)and Collation:utf8mb4_unicode_ciI have modified the database connection in the CodeIgniter app.
I have run the following:
SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ciLastly I have also tried this:
REPAIR TABLE table_name; OPTIMIZE TABLE table_name;
Everything should have been setup properly but yet it doesn't work.
DATABASE SETTINGS:
This is the outcome running the following command:
`SHOW VARIABLES WHERE Variable_name LIKE 'character\_set\_%' OR Variable_name LIKE 'collation%';`
TABLE SETTINGS:
A screeshot of the table structure:
DATABASE CONNECTION:
These are the database connection settings inside database.php (note this is not the only database, there are also others that connect using utf8)
$db['my_database'] = array(
'dsn' => '',
'hostname' => PROJECT_DATABASE_HOSTNAME,
'username' => PROJECT_DATABASE_USERNAME,
'password' => PROJECT_DATABASE_PASSWORD,
'database' => PROJECT_DATABASE_NAME,
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => TRUE,
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8mb4',
'dbcollat' => 'utf8mb4_unicode_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
MY.CNF SETTINGS:
This is the whole content of the file my.cnf:
[mysqld]
default-storage-engine=MyISAM
innodb_file_per_table=1
max_allowed_packet=268435456
open_files_limit=10000
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
[client]
default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4
THE QUESTION:
Do you know why is not working? Am I missing something?
HYPHOTESIS 1:
I am not sure, but the cause of the problem may be this:
As you can see in my.cnf character-set-server is clearly set as utf8mb4:
But after running the query in the database:
SHOW VARIABLES WHERE Variable_name LIKE 'character\_set\_%' OR Variable_name LIKE 'collation%';
The outcome is that character-set-server = latin1
Do you know why is that? Why is not actually updating?
HYPHOTESIS 2:
The application use several different databases. This one is set to utf8mb4 but all the others are set to utf8. It may be a problem even if they are separated databases?
Thank you!
EDIT:
This is the outcome of SHOW CREATE TABLE app_messages;
CREATE TABLE `app_messages` (
`message_id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`project_id` bigint(20) NOT NULL,
`sender_id` bigint(20) NOT NULL,
`receiver_id` bigint(20) NOT NULL,
`message` text COLLATE utf8mb4_unicode_ci,
`timestamp` bigint(20) DEFAULT NULL,
`is_read` enum('x','') COLLATE utf8mb4_unicode_ci DEFAULT NULL,
PRIMARY KEY (`message_id`)
) ENGINE=InnoDB AUTO_INCREMENT=496 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
EDIT 2:
I have run the following command:
INSERT INTO app_messages (message_id, project_id, sender_id, receiver_id, message, timestamp, is_read)
VALUES ('496','322','77','188', '' ,'1473413606','x');
And other two similar with and
They were inserted in the table without problems:
But in the actual app what i really see is: ? (this time only one ? and not 4)
