I was preparing this screenshot in the background in case the Bertram's coded list would reappear.
I am convinced we would get nothing of it, because there is a lot of copy/past pattern, from left to right, from up and down.
Such as finding who Red John were from clues ... there is a big risk to be inconclusive. But hey some of you may still try to do so.
I tried the day we found it to use some symbols font but It got nowhere.
Hope you like it, there is the link.
