unless it's a code within a code, the first 54 letters i checked (before having to get back to work) show no pattern and no discernable frequency. To me, at least.
i rushed through it, but aside from a potental (?) error or two on my part, i think it looks rather like this:
with the letters above representing the symbols but not being the correct letters of the uncoded text of course. caps represent new symbols past the 26th one.
fun stuff, whether it means anything or not
