Title: Fix error variable name.

If a user has a custom charset (not UTF-8), a message should appear, but the variable name is wrong, and we got this message :

```
Notice: Undefined variable: messages in C:\Work\Project\vendor\symfony\symfony\src\Symfony\Bundle\FrameworkBundle\DependencyInjection\Configuration.php line 57
```
