Can you describe more what do you mean by don't work? The screenshot is the default configuration, so unless you are changed the components separator config, I think you should get the same look.

Maybe it's your font(?)

You need to set the component separator option.

require'lualine'.setup {
  options = { component_separators = '|' }
}
