Unown Secret Code

So I've been looking over legendary Pokemon lately, just for fun because they are super cool. And I came across something I guess I already knew, but never thought about.

The Unown.
And no, I didn't spell it wrong, in fact I didn't even know that was how it was spelled until I found them, I had first heard of them from one of the Pokemon Movies, and had just heard 'unknown' not 'unown'

The Unown are a type of Pokemon, with one for every letter of the alphabet, as well as an exclamation point, and a question mark.

If you haven't caught on by what I just said, combined with the title of this post, then let me just blurt it out. Unown, can be used as a secret code!
Here's a picture of them, which came from bulbapedia.bulbagarden.

                               

Now do you see why they make the perfect code? I've actually been working on drawing them out on paper, I don't have a picture, but I made a quick little note in paint:

(In case you can't tell, it says Hi!)
