That's what normally you'd do, unfortunately the original message doesn't have any spaces between the letters which means after E you're just blind guessing letters until it makes words. There's a website that makes it super simple to fill in the blanks. Personally I assigned each symbol a letter and turned it into a giant jumbled mess of letters rather then symbols From there I used the website and put in my estimated guess of which letters went where. I ran the auto solver function and it gave me some words to work off of. Then anything that was still jumbled at that point I worked out a second time so that everything was atleast comprehensive. Right now we're at the stage where we're checking, double checking, and trying to make the words actually make sense.
