How to represent any unicode character in Julia?

Question

I am trying to figure out if there is a list or any documentation which states all the possible unicode characters I can represent and access with \ commands. I know I can do things like \sin or the like but is there a robust list? I tried searching around but didn't find anything. I was specifically looking to see if there was a x hat character or not.

Answer 1

As it turns out, there is a robust list of all possible unicode characters near the bottom of the Julia manual. According to the docs:

You can also get information on how to type a symbol by entering it in the REPL help, i.e. by typing ? and then entering the symbol in the REPL

which is how I figured out how to represent x hat!
