Alertes à l'installation

[felag]

Lorsque j'installe le plugin avec la commande bin/console plugin:install, les alertes suivantes apparaissent:

PHP User Warning (512): Usage of "utf8_unicode_ci" charset/collation detected, should be "utf8mb4_unicode_ci" in /var/www/glpidemo/html/src/DBmysql.php at line 2136

La commande bin/console migration:utf8mb4 effectue la migration.

Il serait bienvenu de ne pas avoir d'alerte à l'installation.
