I use ♪ character in my zsh theme's for prompt. But in tmux, my prompt was behaving weirdly, showing extra spaces, like this:

♪ ~   I can type from here

♪ ~ Instead of here like in zsh, and sometimes when I do stuff like cd

♪ ~   cd ~

♪ ~ cdcd /

♪ ~ ^^These 2 chars just show up but are not actually part of command and not delete-able

I recently discovered that I can set tmux encoding to utf8 by set-window-option -g utf8 on. Doing that, the space problem was gone but ♪ character changed to _. How can I get my ♪ back in tmux?

My zsh-theme:

PROMPT='%{$fg_bold[cyan]%} ♪ %{$fg[blue]%}%c%{$fg_bold[blue]%}$(git_prompt_info)$(git_remote_status)%{$fg_bold[blue]%} % %{$reset_color%}'
