Support LaTeXStrings.jl

[SimonEnsemble]

When I pass in e.g. L"$r/r_o$" as an xlabel in Gadfly, it appears blank. Does Gadfly not support LaTeXStrings?

Julia can generate symbols directly: https://docs.julialang.org/en/v1/manual/unicode-input/ and Tab completion.
Here is a plot I started working on for the Gadfly docs:

Is it possible to convert LaTeXStrings to Julia's unicode symbols? It would nice to be able to copy LaTeX equations from elsewhere and include them in a Gadfly plot. Also Unicode fractions look hella painful compared to \frac{top}{bottom}

[SimonEnsemble]

@tlnagy exactly. Plots.jl takes LaTeXStrings as input.

I haven't tried it, but I think doing latex → Unicode in a separate package is the way to go.

There is a new vscode extension for doing bulk super/subscript:

Julia 1.6 also supports bulk super/subscript: JuliaLang/julia#38649.

I often need LaTeXStrings to fill in the gaps in Unicode. For example, y, z, and θ don't exist as Unicode subscripts. I like to use these to indicate direction.
