How to Use Unicode for X in Your Name

You get yelled at if you use somebody's logo in like your name or something like that because it's their logo. How does that work if I decide to use that X as the end of like my name? Just I wouldn't ever do that because that's dumb. Here's my next question. You're famously using something that looks a lot like a very specific Unicode for X, like a Unicode symbol for X. What happens if we start using that Unicode or does the Unicode X have to get rid of it? They trademarked. Oh my gosh. It's driving bonkers. Imagine being me on a plane just freaking out 35,000 feet while this is going down.
