I wonder if that will have an effect on copyright for the logo. I mean, you can’t just copyright the shape of an existing Unicode character, at least for such a simple one.
Is it really ? It wouldn't be the first time copyright offices would register some nonsense.
They can certainly trademark it for their uses though, and that's the more important protection for a logo.
Or as LaTeX calls it, \mathbb{X}
Some fonts hit it nearly exactly...
I wonder about designer who found this one and throw something together... What was the process and how long it took...
