How do I request the addition of a Unicode symbol?  
I am interested in the symbol “⟋” (U+27CB Mathematical Rising Diagonal) to use in variable names that represent ratios and derivatives. e.g.

```julia
dF⟋dx = 0.2
dF⟋dy = 0.5

```

I tried using the symbol ╱ (U+2571), but it is too big and gets confused with the division operator.

You could do e.g. `dₓF` or `∂ₓF` if you want. ` ⁻¹` is also available. I agree with @jling that it’s still a bit confusing with `╱` or `⟋`.

Another option is

```julia
julia> var"dF⟋dy" = 1+1;

julia> var"dF⟋dy"
2

```

Indeed it could be confusing, however in monotype font (e.g. in VScode), it is rendered much smaller that the division operator. Also, syntax highlight helps to avoid confusion.

That solves the problem. However, shorter identifiers would be desirable.

That is a good solution. In my case, I have variables such as

```julia
df_dup = df_dσmax*dσmax_dup + df_dτmax*dτmax_dup + df_dμ*dμ_dup

```

that I would like to write as

```julia
df⟋dup = df⟋dσmax*dσmax⟋dup + df⟋dτmax*dτmax⟋dup + df⟋dμ*dμ⟋dup

```

Maybe another character could fit better, maybe

```julia
df◢dup = df◢dσmax*dσmax◢dup + df◢dτmax*dτmax◢dup + df◢dμ*dμ◢dup

```
