New icons do not render properly in tmux

[AngelontheRoad]

I just merged #447 and updated all plugins. I tried to use the new nerd font with Mono and Propo and everything works perfectly without tmux. But inside tmux I found that icons were not rendered properly.

inside tmux:

outside tmux is OK:

I found a reddit post that has a similar problem, but no solution works for me.

By the way, I noticed that icons baseline is not a straight line (marked above).😥

Is there any help? Thanks

I use alacritty

three things u need to be careful with:

1. the $TERM set in your terminal and shell
2. the $TERM set for tmux
3. check the $TERM in nvim via :!echo $TERM

I would suggest set it all with xterm-256color.

I should probably set tmux's $TERM with xterm-256color lol, I'm testing sth in other day. Just letting u know u should be careful with that.

My tmux term config is the same with yours, and I've tried to set set-option -g default-terminal "screen-256color" and nothing happened. I have worked with tmux properly until the merge, probably the render problem is caused by tmux or neovim themselves. Anyway, thanks for your reply :)

Can confirm in tmux with Propo variant on wezterm with xterm-256color set.
