No problem :) I mean that people will buy / try to buy π.com, Θ.com, ☃.com, and even 🍤.com (pi, theta, snowman, and fried shrimp characters, if you can't see them). It's inevitable. Even though you can't really type them, people will buy them because they're weird / unique / well recognized. I'm merely saying it's not a problem.
Thank you for your reply. I was fixated on the equation (and xkcd image) from the original comment at the expense of overlooking "weird symbols that I don't even know how to type."
