Please expose each connected player's selected DayZ interface language through the server-side scripting API, for example via PlayerIdentity.GetLanguage().
This would allow server owners to send localized welcome messages, restart warnings and other notifications using NotificationSystem.SendNotificationToPlayerIdentityExtended, without requiring a client-side mod.
Currently, multilingual servers have to duplicate messages in multiple languages or require additional client functionality. Server-side access to the player's language would let scripts select the appropriate translation before sending the notification.
The language should be available after player connection and returned as a documented, stable language identifier.
