Will anyone be going to one of the Unusual Pokémon Sightings in Europe Events? essentially in select European cities Kangaskhan and Unown will spawn pretty frequently. From what people have mentioned you can obtain E,U, R, O, and P Unown.
The event is also taking place in some UK cities, which I never realised. I'll be visiting Manchester this weekend with a couple of mates to hopefully add a couple of rare Pokemon to the Pokedex, along with doing a couple of raids.
