I want to add 𝄫(double flat) and 𝄪(double sharp) to REPL unicode completion, but I don’t know how to do.
I found this in [github](https://github.com/JuliaLang/julia/issues/21646#issuecomment-299280424), but it seems that the Base module does not export the REPLCompletions submodule, and the REPLCompletions module does not export latex\_symbols, so latex\_symbols cannot be modified directly in startup.jl

Perhaps add to your ~/.julia/config/startup.jl :
```julia
using REPL
atreplinit() do repl
REPL.REPLCompletions.latex_symbols["\\dflat"] = "𝄫"
end
```

I don’t think you have to wait for the REPL to be initialized — you should just do it immediately:
```julia
import REPL
REPL.REPLCompletions.latex_symbols["\\dflat"] = "𝄫"
```

It would be reasonable to add `\doubleflat` and `\doublesharp` (or maybe `\flat2` and `\sharp2`, or …?) to the global table in a future version. Just submit a patch to [`REPL/src/latex_symbols.jl`](https://github.com/JuliaLang/julia/blob/aad72458539946bc7f2b1d1f6092f963fed4bd8c/stdlib/REPL/src/latex_symbols.jl#L809-L813). We’re pretty permissive about adding new symbol tab completions.

Thank you for your reply! Very useful.
I have opened a [pull request](https://github.com/JuliaLang/julia/pull/54182) for adding these musical symbols.
