Hi I've just installed ZSH and it looks awesome but git icons are still missing and I don't know what I miss.
What I should do?
Turns out I didn't have powerline font.
You can get it from here
After download, double click to install and set as defalut font & non-ascii font
It worked for me when I unselected the option in iterm preferences to use a different font for non-ASCII text.
Missing icons in this case a patched font isn't installed which is dedicated for showing specific symbols for your shell.
You can either set yourself up easy with an available repo. I should note that these patched fonts are for the Powerline extension and may or may not be compatible with other extensions.
If you wish to patch your own font, however, it's a little more involved:
fontpatcherhomebrew, install fontforge (brew install fontforge).fontforge -script /path/to/fontpatcher.py MyFontFile.ttf
