Why am I seeing this character in Neovim?'

Question

I copy pasted init.lua from Neovim kickstarter.

Now while writing c++ code I am getting the below '?' character inside a box in Neovim

I am using Neovim in Ubuntu subsystem windows 10.

I think some character not supported in WSL, maybe.

Answer 1

I believe the tab part of your listchars option is set to a character that is not supported by your console font.

You could change that characters or characters using:

:set listchars^=-->

More information with: :help 'listchars'.

Of course you could also change the console font and select a font that support that character (Consolas is a standard choice).

Answer 2

Used these below config lines in init.lua to get it resolved.

local o = vim.opt
-- Set your characters here
o.listchars = { space = ' ', tab = '| ' }
o.list = true
o.relativenumber = true
