In PyPlot.jl, how do I get unicode characters to display properly?

Question

I am using Julia (with the IJulia plugin for Jupyter notebooks). How do I get unicode characters to display correctly in my plot?

Here is my code:

using PyPlot
ϕ = linspace(-0.25, 1.25, 100);
f = (ϕ.^2).*(1.0-ϕ).^2;
figure(figsize=(8,5))
plot(ϕ, f, color="purple", linewidth=1.8, linestyle="-")
xlabel("ϕ")
ylabel("f(ϕ)")

However, the plot does not show the unicode character, ϕ, properly:

Even the Pythonic `u'\phi'` doesn't work :( – Dawny33 Apr 05 '16 at 11:41 — Dawny33, Apr 05 '16 at 11:41

PyPlot support LaTeX commands, in this case:

xlabel(L"$\phi$")
ylabel(L"$f(\phi)$")

You can remove the dollar sign as it is not needed. – juliohm Apr 06 '16 at 01:29
