You will need a [Powerline-patched font][patching] for this to work, unless you enable the compatibility fallback option:

set -g theme_powerline_fonts no

[I recommend picking one of these][fonts]. For more advanced awesome, install a [nerd fonts patched font][nerd-fonts], and enable nerd fonts support:

sudo apt-get install fonts-powerline
set -g theme_nerd_fonts yes
