braille code here differs from wikipedia standard

The here assumed braille code for "w" seems to be different from the standard code as given by wikipedia (https://en.wikipedia.org/wiki/Braille) according to wikipedia it should be [[0,1],[1,1],[0,1]] here it is given as [[0,1],[1,1],[1,1]]. That can be highly confusing when trying to decifer the predetermined lookup-functions for this excercise.
