Answer 1

Installing a powerline patched font will solve this. This official documentation provides description about installing poweline fonts.

There are two ways to enable powerline patched font in iTerm2.

1. Set a powerline patched font as default.

2. Set a powerline patched font for only Non-ASCII characters and use another font for code.

Bonus:

• Collection of powerline patched fonts
• Awesome oh-my-zsh themes
  • Spaceship ZSH
  • Buller Train
  • powerlevel9k

Answer 2

The solution is to use a prepatched font. Point 6 of this article describes the solution.

Answer 3

On Windows - just * download some Powerline font like: https://github.com/abertsch/Menlo-for-Powerline/raw/master/Menlo%20for%20Powerline.ttf
* Install it by clicking the file twice
* Choose the new font in properties
That's it!

On Mac - the previous answer in totally correct, just install and choose an appropriate font.

Answer 4

This has fixed the issue. Just select Use built-in Powerline glyphs and use Inconsolata for Powerline font.

Answer 5

1. git clone https://github.com/powerline/fonts (clone it anywhere, You can remove cloned dir after step-4)
2. cd fonts
3. ./install.sh
4. Open iTerm2->Preferences->Profiles->Text->Change Font-> Meslo LG S DZ Regular for Powerline

EDIT: If you are not using iTerm you can simply change the default macOS Terminal Preferences. (Thanks to Kewal Shah)

Reopen the terminal and you are done.
