Some utf8 character widths were miscalculated in the terminal component

In the demo code, when ZSH_THEME was using powerlevel9k, character widths were miscalculated, causing the right toolbar to span lines

Sorry @nxsre that I have taken so long to look at this - just busy at work at the moment. I hope to get to it soon

Hi @nxsre - it's been a long time since I promised to look at this, so I understand if you've moved on to other projects. If this bug is still a problem for you, would you be able to send me some information that would help me reproduce it? I am testing on Ubuntu 20.04 with gnome terminal, zsh, oh-my-zsh and the powerlevel9k theme running the gowid demo inside and outside tmux, but don't see any screen corruption.

My system is macOS 10.14.6, I just tested it, and I still have this problem

Again, I verified that the problem appeared to be only on macOS terminals and that CentOS 7 was fine
