Capitalize french accent support

[johackim]

Description

Hello,

Thanks for creating Telescope.nvim !

I try to search files with accents. But if the file has a capitalize accent character, it will not appear on the results.

Exemple widh a markdown file : Écriture.md.

If I search écriture, it not appeear.

Neovim version

NVIM v0.6.1
Build type: Release
LuaJIT 2.1.0-beta3

Operating system and version

Arch Linux

checkhealth telescope

telescope: require("telescope.health").check()

## Checking for required plugins
  - OK: plenary installed.
  - OK: nvim-treesitter installed.

## Checking external dependencies

  - OK: fd: found fd 8.3.2

## ===== Installed extensions =====

Steps to reproduce

Expected behavior

Actual behavior

If I search without a capital accent letter, I can't find my file.

Minimal config

vim.cmd [[set runtimepath=$VIMRUNTIME]]
vim.cmd [[set packpath=/tmp/nvim/site]]
local package_root = '/tmp/nvim/site/pack'
local install_path = package_root .. '/packer/start/packer.nvim'
local function load_plugins()
  require('packer').startup {
    {
      'wbthomason/packer.nvim',
      {
        'nvim-telescope/telescope.nvim',
        requires = {
          'nvim-lua/plenary.nvim',
          { 'nvim-telescope/telescope-fzf-native.nvim', run = 'make' },
        },
      },
      -- ADD PLUGINS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
    },
    config = {
      package_root = package_root,
      compile_path = install_path .. '/plugin/packer_compiled.lua',
      display = { non_interactive = true },
    },
  }
end
_G.load_config = function()
  require('telescope').setup()
  require('telescope').load_extension('fzf')
  -- ADD INIT.LUA SETTINGS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
end
if vim.fn.isdirectory(install_path) == 0 then
  print("Installing Telescope and dependencies.")
  vim.fn.system { 'git', 'clone', '--depth=1', 'https://github.com/wbthomason/packer.nvim', install_path }
end
load_plugins()
require('packer').sync()
vim.cmd [[autocmd User PackerComplete ++once echo "Ready!" | lua load_config()]]

If you are using fzf-native, its a fzf-native bug because i do not yet have support for utf8 case. Its on my roadmap: https://github.com/nvim-telescope/telescope-fzf-native.nvim#todo

I was already working on it once and got it working but its made the performance way slower because i implemented it with additional allocations.

I will go back to it pretty soon because i have a couple of new ideas

Hello @Conni2461, thanks for your reactivity.

I have this issue with any extensions.

Hope this will be fixed soon :)
