Question

as the image shows , after installing the powerline for vim, some symbols are not working.

--For all the noobs, with attention deficit, like my self.

I had the same issue, the solution was much more basic than than installing the fonts, but was not mentioned anywhere else: manually setting the fonts in your terminal (still need to make sure you have the fonts installed).

In iTerm2: iTerm > preferences > profiles > text > Regular font & non ASCII font.

In Terminal : Terminal > preferences > profiles > text > fonts
