CRLF and charset utf-8-bom

Description

On work, we are using an editorconfig with the following content:

[*]
charset = utf-8-bom
end_of_line = crlf

as we have a lot of developers using windows.

However, I am using macOS, and I am having some issues with gitsigns marking every line as changed. Maybe I am doing something wrong.

I tried to set core.autocrlf to different values, and none of them seems to change anything.

Neovim version

NVIM v0.11.0-dev-283+gfe5d1279a

Operating system and version

macOS 14.5 (23F79)

Expected behavior

I would expect it to not show any changes, as I haven't done any changes to the file.

Actual behavior

It shows that all lines are changed like this:

Also, trying to view the diff in a popup with :Gitsigns preview_hunk, this happens:

Minimal config

for name, url in pairs{
  gitsigns = 'https://github.com/lewis6991/gitsigns.nvim',
  -- ADD OTHER PLUGINS _NECESSARY_ TO REPRODUCE THE ISSUE
} do
local install_path = vim.fn.fnamemodify('gitsigns_issue/'..name, ':p')
if vim.fn.isdirectory(install_path) == 0 then
vim.fn.system { 'git', 'clone', '--depth=1', url, install_path }
end
vim.opt.runtimepath:append(install_path)
end

require('gitsigns').setup{
  debug_mode = true, -- You must add this to enable debug messages
  -- ADD GITSIGNS CONFIG THAT IS _NECESSARY_ FOR REPRODUCING THE ISSUE
}

-- ADD INIT.LUA SETTINGS THAT IS _NECESSARY_ FOR REPRODUCING THE ISSUE

Steps to reproduce

Create a file with some content with LF line endings. Doesn't matter.

Paste this into a .editorconfig:

[*]
charset = utf-8-bom
end_of_line = crlf

Open the file again and notice it shows all lines as diffed.
