In the current (August 2017) event going on in Europe, Kangaskhan and Unown are available in Europe, and in large masses. From Trainer Tip's Video I've learned that during the Chicago event Unown were also available, but only the letters that spell out "Chicago" ('a', 'c', 'g', 'h', 'i', and 'o') and he said that the same might happen in the current event (only certain letters of Unown being available).
Is this the case, and if so what letters are available and where (since the event takes place in many different cities across Europe)?
