Errors accepting suggestions with latin1 encoded files

[higorhgoncalves]

I am having errors when accepting suggestions in latin1 encoded files.

Error executing vim.schedule lua callback: vim/_editor.lua:0: encoding: expected ?, got latin1. Info: invalid encoding
stack traceback:
[C]: in function 'error'
vim/shared.lua: in function 'validate'
vim/_editor.lua: in function 'get_line_byte_from_position'
/usr/share/nvim/runtime/lua/vim/lsp/util.lua:356: in function 'apply_text_edits'
...re/nvim/lazy/copilot.lua/lua/copilot/suggestion/init.lua:542: in function ''
vim/_editor.lua: in function <vim/_editor.lua:0>

this is my config:

{
	"zbirenbaum/copilot.lua",
	cmd = "Copilot",
	event = "InsertEnter",
	config = function()

		require("copilot").setup({
			panel = {
				enabled = false,
			},
			suggestion = {
				enabled = true,
				auto_trigger = true,
				hide_during_completion = true,
				debounce = 75,
				trigger_on_accept = true,
				keymap = {
					accept = "<M-l>",
					accept_word = "<M-Right>",
					accept_line = "<M-C-Right>",
					next = "<M-]>",
					prev = "<M-[>",
					dismiss = "<C-]>",
				},
			},
			copilot_model = "gpt-4o-copilot",
		})
	end,
}

I will investigate, though I would have assumed #336 would have handled this issue as they seem to be the same.

I am unable to replicate this but reading the nvim function doc it expects to have a utf-x encoding in that call and it is getting latin1.
Could you do a test on your end by editing the source file ../lazy/copilot.lua/lua/copilot/suggestion/init.lua line 542:
vim.lsp.util.apply_text_edits({ { range = range, newText = newText } }, bufnr, encoding)
And changing it to one of the following (until one works):
vim.lsp.util.apply_text_edits({ { range = range, newText = newText } }, bufnr, 'utf-16')
vim.lsp.util.apply_text_edits({ { range = range, newText = newText } }, bufnr, 'utf-8')
vim.lsp.util.apply_text_edits({ { range = range, newText = newText } }, bufnr, 'utf-32')

If one of them works, please let me know which one, thank you!

All of them worked!!
I also tried to do the readme faq for "Multiple offset encodings warning", but i couldn't get it to work, I tried to apply the code without nvim-lspconfig, as i am not using it in nvim 0.11, I am using the default lsp config from nvim.

Thanks for testing it, I will add a fallback so that if the encoding is not utf-# to use utf-8

Another question before I make a change, when you have your file open, what does this yield in neovim:
:lua print(vim.api.nvim_get_option_value("encoding", { scope = "global" }))?

[higorhgoncalves]

it prints "utf-8"

Awesome, fix is done, thanks for the help!
