when trying to install kubeps1 with zinit I am getting the following error

probably your locale / lang settings aren't utf8: #80

I confirm that should fix it. Add the same issue.
Editing my zshrc file with

export LC_ALL=fr_FR.UTF-8
export LANG=fr_FR.UTF-8 

fixed it

Thank you for the suggested fixes.

I don't why this does't work when I ssh to remote wsl from Mac iTerm. Finally I stopped error message with:

# ~/.zshrc

UNICODE_TEST=$(echo '\u2190' 2>/dev/null);
if [ -z $UNICODE_TEST ]; then
    KUBE_PS1_SYMBOL_DEFAULT='x'
fi

source $ZSH/oh-my-zsh.sh

You have to put the LC_ALL and LANG at the top.
