Description

Icon rendered small on kitty terminal due to following nbsp.

See kovidgoyal/kitty#1463, kitty will only render icons as full-width when it is followed by at least on space.

Screenshots:

• On kitty:

  

• Same tmux pane on alacritty:

  

Setting opts.nbsp to plain space seems to fix this issue, but it will break the live_grep finder (e.g. cannot jump to the correct file and location), not sure if that breaks other functionalities.

Tried with opts.nbsp = ' \xe2\x80\x82' (space followed by nbsp), but that makes the gap between the icon and the text too large.

Could you help me figure out how can I have full-width nerd font icons on kitty without breaking existing functionalities? Thanks in advance!

Take a look at the default options section:

require('fzf-lua').setup {
  -- padding can help kitty term users with
  -- double-width icon rendering
  file_icon_padding = ' ',
}

Thank you for your assistance! I attempted to adjust the opts.file_icon_padding, but encountered a similar issue when setting opts.nbsp to ' \xe2\x80\x82' – the space between the icon and the text appeared slightly too large.

I'm very grateful to @kovidgoyal for addressing this specific case in Kitty! With the recent patch he added, using kitty nightly now allows for a seamless full-width icon display, whether followed by a space or a nbsp. Now setting opts.nbsp to '\xc2\xa0' solves the issue.
Setting it other invisible values, e.g. '\xe2\x80\x82' (the default nbsp value) does not work, however, but it should be easy to solve.
