It is the Autobot language from the G1 series and has been used in other continuities. The Decepticons have a different text and Ancient Cybertronian is completely different from either of them. And yes, that is canon.
Well I'm sorry that I didn't correct that person. But in my opinion, I would assume everyone would know that a little gal like me couldn't possibly be able to make up the cybertronian alphabet and that Habro or whoever owned it.
you also didn't credit where you got it from. i'm just giving you some advice. Credit where you found things, and state right up front that you didn't make it. people will accuse you of art theft and that's one of the worst things that can happen here to someone.
That's actually the Autobot Alphabet from G1. I have both the Autobot and Decepticon glyphs posted [link] , as well as the Language of the Primes [link] if you would like to see. The Maximals and Predicons also have their own glyphs, which I have as well.
