I don’t know if its of any relevance but…
– I realised there are 2156 \s, 2156 /s and 8624 |s
– 8624 is 4 lots of 2156
– this could be a coincidence, on second thought its probably not
– so that tells us that it isn’t a substitution of some sort where variations of the characters mean something but rather teh positioning of the letters and the distance between them could be more important
BUT, I haven’t solved it yet so this is just throwing out wild guesses.
