The Tahm Kench Pages

This is a quick question for any Rioter on Narrative, or someone who is a better analyzer than I (which isn't saying a whole lot).

So I think everyone has, at this point, seen "The River King" and Tahm seemingly reading from pages floating through the river, written in a (probably) ciphers Runeterrian language. While it is easy to make out a couple of repeating strokes, the faded characters make it impossible to "read". So, does anyone know if the scripts actually mean anything, or were just Runeterrian lorem ipsum?

Sorry if this is an obvious question, but it's been bugging me for a while.
