How do I use nvim --server? I'm on Windows 10 and I installed nvim with scoop. I try these commands:

> nvim --version
NVIM v0.10.0
Build type: Release
LuaJIT 2.1.1713484068
Run "nvim -V1 -v" for more info

> nvim --listen ~/.nvim-cache/server.pipe

As expected, nvim launches in my command prompt window. I switch to another command prompt:

> nvim --server ~/.nvim-cache/server.pipe --remote somefile.txt

nvim launches another instance in my command prompt window instead of opening that file in the first instance. There's a flash of some garbled characters (starting with +qm+54) and then the file displays, but that happens every time I start nvim.

I've also tried using %USERPROFILE%\.nvim-cache\server.pipe and ~/server.pipe instead of ~/.nvim-cache/server.pipe. I tried editing and saving the pipe in nvim (the contents aren't modified after launching --server).

Nothing in the documentation indicates this feature is platform-specific, so what am I doing wrong?

How can I use --servername and --remote in neovim? is related, but asking about vim's clientserver feature in neovim whereas I'm trying to use nvim's version of this paradigm.
