I change the font of ticks supported by GR: [Fonts — GR Framework 0.72.9 documentation](https://gr-framework.org/fonts.html). Since the default backend for plots package is GR, I think I can use these fonts. However, when I save the figure as pdf file, some symbols can not display normally, for example, the math symbol “-”. This my code and output which is pdf format.

```julia
using Plots
using LaTeXStrings
x = -2*π:0.01:2*π
y = @. sin(x)

default(tickfontsize=12, guidefontsize=13,
        legendfontsize=12,
        tickfontfamily="Helvetica")
p = plot(x, y)
xlabel!(L"$xxx$ variable")
ylabel!("E")
savefig("plot.pdf")
p

```

Is there any method to deal with? I have no ideal with this.
