PDF Manual Symbol Problems

[Ronneesley]

Hello,
Some symbols in manual (PDF) isn't appearing. See some the occurrences:

Function composition and piping

The symbol: ∘

(sqrt ∘ +)(3, 6)

Repeated Evaluation: Loops

The symbol: ∈

for s ∈ ["foo","bar","baz"]
     println(s)
end

It can be trouble for beginners.

Can you reopen this at https://github.com/JuliaDocs/Documenter.jl ? It is possible that this was fixed by JuliaDocs/Documenter.jl#1066 but that might not have been deployed yet.
