Ekko login screen hidden message?

I came across the log in screen for the new champion Ekko. I noticed the writing in the background on the sheets of paper that was in symbols. I looked at the Egyptian symbols but couldn't find any that similar to them. I am having trouble finding which symbols these are, and could use some help on decryption them. They give us a full view of the symbols for a breif moment, so i think riot has some easter egg or something they want us to find. Reply what you think it is Thanks~ArrowPvP
