Underline colors not working on Window Terminal

[mmgeorge]

1. Graphical issue inside a terminal pane (eg. something does not look as it should)

zellij --version: zellij 0.39.2
(I also tried checking out 7f87d93a430a47c82ce3f177a6a2609d3f6abadeand & saw the same thing)

Further information

Undercurls are working great, but I seem to be hitting some problems with underline colors in WSL + Window Terminal 1.19/1.20:

echo -e "\x1b[58:5:32m\x1b[4mtest\x1b[59m\x1b[24m"
echo -e "\x1b[4:3mTest\x1b[24m "

How undercurls should be enabled for Zellij in Windows Terminal?

I can see them in Neovim on tmux by a terminal override, but not in Zellij.

Any hint?

@steakhutzeee for me they work on the latest version without any additional configuration, just the colors that aren't working for me

[steakhutzeee]

With your commands they work for me too. It's in nvim that they are now working.
I was able to let them work inside tmux but not outside with a terminal override. Any idea how to do this with Zellij?

[mmgeorge]

Sorry @steakhutzeee I'm not sure what would be causing them to work in tmux but not zellij. On my end at least they just work by default with the latest zellij.

Can confirm, works well under WinTerm (after using the tweak below), but not under WinTerm + Zellij.

I had to execute the following line to make the colored underline work (added it to my ~/.zshrc for convenience)

$ set -as terminal-overrides ',*:Setulc=\E[58::2::%p1%{65536}%/%d::%p1%{256}%/%{255}%&%d::%p1%{255}%&%d%;m'´

However this does not fix the colored underlines when using Zellij via WinTerm

This should be tmux config, not zsh. Correct?

For me, I've been acting strange on my side. Unexpected behavior occurs only in neovim.
