How to type x̂ or ŷ in Julia?

I was reading through a tutorial and it makes use of x hat and y hat. I am unable to create those characters locally and they do not appear in the unicode character list I saw. Usually I would do \xhat to create the unicode character but that again does not seem to exist in this case.

Type x\hat and press tab to get what you want. You can also search the character in the Julia REPL:

help?> x̂
"x̂" can be typed by x\hat<tab>

Note that in this case this sequence consists of two characters:

julia> collect("x̂")
2-element Vector{Char}:
 'x': ASCII/Unicode U+0078 (category Ll: Letter, lowercase)
 '̂': Unicode U+0302 (category Mn: Mark, nonspacing)

Of which the second is a combining diacritical mark.
