PHPUnit - assertTablesEqual encoding accents - encoding

Question

I'm using:
PHPUnit 3.6.12 / PHP 5.3.1 / MySQL 5.1.30
I'm trying to compare the value inserted by a function in a database with the value I expect.
The value is a string CONTAINING ACCENTS.
So I created a xml file: expectedValue.xml (file encoded in UTF-8)
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<table name="MyTable">
<column>MyColumn</column>
<row>
<value>résumé</value>
</row>
</table>
</dataset>
Here is the code in the test method (file encoded in UTF-8 too)
public function testSave()
{
// this function saves the data in an UTF-8 database
save('résumé');
$queryTable = $this->getConnection()->createQueryTable('MyTable', 'SELECT MyColumn FROM MyTable') ;
$expectedTable = $this->createXMLDataSet('expectedValue.xml)->getTable('MyTable') ;
$this->assertTablesEqual($expectedTable, $queryTable) ;
}
And here is the result I get:
Failed asserting that
MYTable
MyColumn
résumé
is equal to expected
MyTable
MyColumn
résumé
Does anyone know where this encoding problem may come from ??
Thanks !!

Could possibly be the database connection
When you're connecting to MySQL (in your getConnection() method), you need to make sure you explicitly set UTF-8.
$pdo = new PDO(
'mysql:host=hostname;dbname=defaultDbName',
'username',
'password',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8")
);
If you're not using MySQL, you can search for ways to set the charset.
