Error "Reverse range in character class"

[Perry3D]

Description

Hi

when i use :Telescope find_files and search for a character followed by a "-" character i get the following error message:

Error executing vim.schedule lua callback: Vim:E944: Reverse range in character class
stack traceback:

	...ck\packer\start\telescope.nvim/lua/telescope/pickers.lua:1246: in function 'cb'
	vim.lua:285: in function <vim.lua:285>

It somehow depends on the current pwd. When I start neovim inside the nvim configuration directory everything works fine. But if the current pwd is my c++ project I get this error.

Tried it with the minimal config and my own config.

Neovim version

NVIM v0.6.0
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

Can you try #1586 ?

[Perry3D]

Tried commit 96e299d and i still get the error.

As an additional hint: I can only reproduce it when opening directories with a huge amount of files. In my case around 80k files.

[Conni2461]

Is this still happening?

I tried to reproduce this issue but only works with huge amount of files, says kinda nothing. I can trigger this error "Reverse range in character class" with the following setup.

i setup this folder_name="[u-a]" && mkdir -p "$folder_name" && touch "$folder_name/dummy"
and then open neovim and run :lua print(vim.fn.expand("[u-a]")) but it doesn't happen with telescope because we escape before passing into vim.fn.expand like this :lua print(vim.fn.expand(vim.fn.fnameescape("[u-a]")))

Can you at least tell me the full file path that is currently selected when the error is thrown?

I encounter the error with the setup described

Error executing vim.schedule lua callback: Vim:E944: Reverse range in character class

        vim/_editor.lua: in function <vim/_editor.lua:0>

as far as I can tell, the function fnameescape isn't being used at the location of the crash, lua/telescope/from_entry.lua:33
probably because this code is newer than the earlier conversation.
