Tmux misinterpret special characters

[yash-saini275]

I tried this customization on latest version of parrot os. It works fine on bash shell. But when I open the tmux session ┌── this is misinterpreted as ____(4 dashes).

Hi there,

Basically tmux is using a different PS1 variable from your .bashrc file.

In your .bashrc file, look for this line:

if [ "$color_prompt" = yes ]; then
    PS1="\[\033[1;32m\]\342\224\214\342\224\200$([[ $(/opt/vpnbash.sh) == *"10."* ]] && echo "[\[\033[1;34m\]$(/opt/vpnserver.sh)\[\033[1;32m\]]\342\224\200[\[\033[1;37m\]$(/opt/vpnbash.sh)\[\033[1;32m\]]\342\224\200")[\[\033[1;37m\]\u\[\033[01;32m\]@\[\033[01;34m\]\h\[\033[1;32m\]]\342\224\200[\[\033[1;37m\]\w\[\033[1;32m\]]\n\[\033[1;32m\]\342\224\224\342\224\200\342\224\200\342\225\274 [\[\e[01;33m\]??\[\e[01;32m\]]\\$ \[\e[0m\]"
else
    PS1='┌──[\u@\h]─[\w]\n└──╼ \$ '
fi

And what you need to do is update both PS1 variables. This is where your terminal prompt gets its style from, so you can put almost anything there. Replace those lines with this:

if [ "$color_prompt" = yes ]; then
    PS1="\[\033[1;32m\]\342\224\200$([[ $(/opt/vpnbash.sh) == *"10."* ]] && echo "[\[\033[1;34m\]$(/opt/vpnserver.sh)\[\033[1;32m\]]\342\224\200[\[\033[1;37m\]$(/opt/vpnbash.sh)\[\033[1;32m\]]\342\224\200")[\[\033[1;37m\]\u\[\033[01;32m\]@\[\033[01;34m\]\h\[\033[1;32m\]]\342\224\200[\[\033[1;37m\]\w\[\033[1;32m\]]\$\[\e[0m\]"
else
    PS1="\[\033[1;32m\]\342\224\200$([[ $(/opt/vpnbash.sh) == *"10."* ]] && echo "[\[\033[1;34m\]$(/opt/vpnserver.sh)\[\033[1;32m\]]\342\224\200[\[\033[1;37m\]$(/opt/vpnbash.sh)\[\033[1;32m\]]\342\224\200")[\[\033[1;37m\]\u\[\033[01;32m\]@\[\033[01;34m\]\h\[\033[1;32m\]]\342\224\200[\[\033[1;37m\]\w\[\033[1;32m\]]\$\[\e[0m\]"

That should work for you

No it still persists. I guess its related to some character encoding. I am using 3.1b version of tmux and they have done something with character encoding.

And if i open tmux in vscode it works fine there is no misinterpretation of characters. So I think definitely it is related to characters.

I finally got the solution run tmux with -u flag. and it works fine. Or better create an alias as: alias tmux='tmux -u'.

awesome! glad you figured it out. I'll keep note of it and see if anyone else has that issue
