I mean the J is excluded entirely, all other letters are there as either lowercase or uppercase. Counting them as separate characters leaves it with 40-50 unique characters.
It may be possible that upper/lowercase represent different characters entirely, but I'm just assuming that they represent the same character. That would leave two missing.
