How can databases be created with utf8_unicode_ci collation as default?

When new databases are created in cPanel they don't get the desired utf8_unicode_ci collation but instead utf8_general_ci even though the former one should be the default collation.

The databases are created in the control panel but not phpMyAdmin.

How can I make the database creation tool create the db with the utf8_unicode_ci collation?

There is also one thing worth mentioning and that is the 'Server connection collation' in phpMyAdmin general Settings on the dashboard, which is utf8_general_ci but should perhaps be utf8_unicode_ci. Please advice me on of how to make it so.

Output from the character and collation variables query:

Code:
mysql> show variables like "%character%";show variables like "%collation%";

Charset in my.cnf:

Code:
[mysqld]
init_connect='SET collation_connection=utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci

Hello :)

Adjusting the default encoding and collation in /etc/my.cnf should result in the behavior you are expecting. For example, I added the following entries to the /etc/my.cnf on a test server and restarted MySQL:

Code:
collation_server=utf8_unicode_ci
character_set_server=utf8
Upon creating a new database, the correct values were used:

Code:
mysql> show variables like "character_set_database";
+------------------------+-------+
| Variable_name          | Value |
+------------------------+-------+
| character_set_database | utf8  |
+------------------------+-------+
1 row in set (0.00 sec)

mysql> show variables like "collation_database";
+--------------------+-----------------+
| Variable_name      | Value           |
+--------------------+-----------------+
| collation_database | utf8_unicode_ci |
+--------------------+-----------------+
1 row in set (0.00 sec)
Are you sure "utf8_general_ci" is output with the above command for new databases?

Thank you.

utf8_unicode_ci

is the output for collation_database like displayed in my previous post, with the command:

Code:
mysql> show variables like "%character%";show variables like "%collation%";

I see it in phpMyAdmin.
That does not mean your databases are created with the "utf8_general_ci" collation. It's just what is configured for PHPMyAdmin itself. You can change that value in PHPMyAdmin by selecting a different collation in the drop down box for your session if necessary.

Thank you.

:confused:

Then why does it show the collation utf8_general_ci for the tables in phpMyAdmin, I thought it should be the unicode one?

Are you sure those databases/tables were created after you modified the default collation in your /etc/my.cnf file? You can open a support ticket if you want us to take a closer look:

Submit A Ticket

You can post the ticket number here so we can update this thread with the outcome.

Thank you.

Yes I'm sure!

I've created several databases in cPanel accounts on the server after the configuration changes few months back. All of them seem to have the utf8_general_ci collation instead of utf8_unicode_ci when displayed in phpMyAdmin.

I must be misunderstanding something.

But right now I'm not sure if I should submit a support ticket.

This a screenshot of the structure view of the most recent database in phpMyAdmin, created months after the changes:

I have the same problem!

MySQL 5.1

conf look like this:

Code:
[mysqld]
.....
.....
default-table-type=MyISAM
default-storage-engine=MyISAM
collation-server=utf8_unicode_ci
character_set_server=utf8
skip-character-set-client-handshake
And still, when I try to create a table, they are created using "utf8_general_ci" instead of "utf8_unicode_ci".


In your example, and the way you showed: "show variables like "collation_database";", you are not really showing us the table status, to be able to see the "Collation" under which your database/table is created.

Any help appreciated to what is causing this.

To update, this issue was resolved by adding the following to the end of the /usr/local/cpanel/base/3rdparty/phpMyAdmin/config.inc.php file:

Code:
// Custom Server Settings
$cfg['DefaultConnectionCollation'] = 'utf8_unicode_ci';
Thank you.
