Why can't we use $MathJax$ or other characters in username?

I'd recommend this on SE network.

    $\begingroup$ For simple enough MathJax expressions, you can use Unicode characters to mimic it in a username. For example, I'm pretty sure "ℶ₁=ℵ₁" would be a perfectly acceptable (though perhaps annoying) username. $\endgroup$

Besides the fact that it seems totally unnecessary, I'd imagine it's a combination of

  • It would make @-replies basically impossible.
  • Most sites on the SE network don't have MathJax (which, by the way, is not the same thing as LaTeX).
  • Too much hassle for the SE team to implement compared to the "benefit".

You already can use markdown, MathJax, images, etc. in your "About Me" section - an impressive amount of expressive ability. What is so bad about requiring a single aspect of your account to be plain text?

  • $\begingroup$ Aah! I also wanted to ask about special characters ... shifted numerics $\endgroup$
