MySQL : modification de l'encodage de la connexion

Il arrive malheureusement trop souvent que l'on doive traiter avec des bases de données qui ne sont pas encodées en UTF8.
Et lorsque l'on souhaite récupérer les données, on se retrouve avec plein de caractères bizarres comme : é en lieu et place des caractères accentués (é dans le cas présent).

Un remède consiste à modifier l'encodage de la connexion au serveur MySql :

SET NAMES 'latin1';

La liste des encodages disponibles est accessible via la commande :

SHOW CHARACTER SET;
