No, summons are still characters internally despite not existing at world creation time.
If you place 3 skeletons for an encounter they are still three instances of the same template, just instantiated sooner than summons and referenceable via names (unlike summons).
Other than that, summons can still trigger events, and the CharacterXyz() functions handle them just fine.
The only difference is that their lifetime is tied to a cooldown. I dont see any reason why they wouldn't be characters.
