How to compile special characters in function name, like δ, by Documenter.jl?

Hello, I encountered an issure while writing my documentation by Documenter.jl. And it seems that there are no corresponding examples in the official documentation.

There exists a ∇ character in my function name and it’s description：

@doc raw"""
    ∇normedVoltage(z, ϕs::Float64, ϕ2s::Float64, r::Float64, h1::Int64, h::Int64, circum::Float64)::Float64

Gradient of normalized voltage.
"""
function ∇normedVoltage(z, ϕs::Float64, ϕ2s::Float64, r::Float64, h1::Int64, h::Int64, circum::Float64)::Float64
    res = cos(ϕs - 2 * h1 * π * z / circum) + r * h * cos(ϕ2s - 2 * h1 * h * π * z / circum)
    -2 * h1 * π / circum * res
end
@doc raw"""
    ∇normedVoltage(z, par::ParDBRF)::Float64

Gradient of normalized voltage.
"""
function ∇normedVoltage(z, par::ParDBRF)::Float64
    ∇normedVoltage(z, par.ϕs, par.ϕ2s, par.r, par.h1, par.h, par.circum)
end

I wrote the following content in the markdown file in folder docs/src/ and run julia --project make.jl：

```@docs
∇normedVoltage
```

But something was wrong. And if I don’t write the \nabla character , the compilation is OK.

I use unicode extensively in my packages, and never run into any special trouble just because of unicode. This looks like you’re just not exporting ∇normedVoltage, so you have to write this in the docs:

```@docs
DoubleRFs.∇normedVoltage
```
