Ok, reply to myself.

I've found a weird solution.

I'm using EMS MYSQL Manager to manage my silverstripe db. When I export the database, it opens "sql monitor" with all the sql code and creates a .sql file too. In that file the charset isn't correct.
So, when I import the db in another host, I copy the text on the sql monitor (in the program I use) instead that .sql file.

I'm not sure if I explained it correctly, my english isn't really good :)

Hi @all,

I had the same problem...

Some MySQL-servers created a ISO connection by default.

So, you must call

mysql_query("SET NAMES 'utf8'");

directly after the connection to the db.

=> A parameter for enforcing a utf8-connection would be pretty useful.

Just for reference, here's the ticket relating to the issue, with an explanation from Sam, the project lead: Unfortunately we can't simply switch connections by default without effect on legacy data, although I agree that it would be a nice optional setting for new sites in the meantime.

a usual source of utf-8 problems with mysql is the mysql connection (mysql needs to be set to utf-8 on a per connection basis).
2 solutions:
Add these lines to your [mysqld] - section of my.cnf:
default-character-set = utf8
default-collation = utf8_general_ci
init_connect='SET NAMES utf8'

or run the following sql commands directly after connecting to the database:
mysql_query( 'SET NAMES utf8', $db_ss );
mysql_query( 'SET CHARACTER SET utf8', $db_ss );
mysql_query( "SET COLLATION_CONNECTION='utf8_general_ci'", $db_ss );

Just a simple and clean solution:
<br >
<br >Create a class:
<br >class UTF8MySQLDatabase extends MySQLDatabase {
<br >
<br >   public function __construct($parameters) {
<br >      parent::__construct($parameters);
<br >      $this->query("SET CHARACTER SET 'utf8'");
<br >      $this->query("SET NAMES 'utf8'");
<br >   }
<br >}
<br >Add something like that to your "mysite/_config.php":
<br >global $databaseConfig;
<br >$databaseConfig = array(
<br >   "type" => "UTF8MySQLDatabase",
<br >);
<br >
<br >Cheers,
<br >Malte

I think you mean;

class UTF8MySQLDatabase extends MySQLDatabase {
   public function __construct($parameters) {
      $this->query("SET CHARACTER SET 'utf8'");
      $this->query("SET NAMES 'utf8'");

Add something like that to your "mysite/_config.php":

global $databaseConfig;
$databaseConfig = array("type" => "UTF8MySQLDatabase");

I have excatly the same problem!

I did try the following steps:

1) I changed the my.cnf file, like described by Radon.
2) It did place a file 'UTF8MySQLDatabase.php' in the code directoty of mysite and did change the connection type to "UTF8MySQLDatabase" like described by mattclegg.

Unfortunately nothing of this did help :(

Here the the original website (old server):
And here is the migrated website (new server):

What's wrong?
I have no idea :(
