How do I display icons in VIM

I'm looking to set up vim to display icons in my NerdTree pane.

I have it set as:

let g:NERDTreeIndicatorMapCustom = {                                                                                                    
                        \ "Modified"  : "✹",                                                                                            
                        \ "Staged"    : "✚",                                                                                            
                        \ "Untracked" : "✭",                                                                                            
                        \ "Renamed"   : "➜",                                                                                            
                        \ "Unmerged"  : "═",                                                                                            
                        \ "Deleted"   : "✖",                                                                                            
                        \ "Dirty"     : "✗",                                                                                            
                        \ "Clean"     : "✔",                                                                                            
                        \ 'Ignored'   : '☒',                                                                                            
                        \ "Unknown"   : "?"

It would be similar to how VSCode is set. Which display correctly here but not in my terminal it just has [x].

Is there a setting I can change?

I'm trying to set it up so that each file type has its own icon and git status for the file is visually shown.

I ended up installing a nerd font and airline now everything works.
