Programmatically know if the current font has the powerline patch

I use vim with vim-airline that can use patched fonts for additional awesomeness.

vim-airline

I also use fish shell (if you want read zsh here since it is equivalent for the analysis) with a theme that also uses patched fonts.

I save my dotfiles online and I use them in different systems. But in some of them I don't have a patched font. I would really love to have generic dotfiles that for example do not use a theme that needs patched font if the current font is not patched. Also in my vimrc I disabled the use of patched characters for vim-airline because of this.

Is there a way to programmatically know if the font that is currently in use is a patched one so that is possible to write generic dotfiles that fit perfectly in all the situations?

You can do this the other way around and only enable Powerline fonts for known machines in your .vimrc e.g.

let hostname = substitute(system('hostname'), '\n', '', '')
let patched_font_hosts = ['host1', 'host2', 'host3']   " List of know patched hosts
if(index(patched_font_hosts, hostname) >= 0)
  let g:airline_powerline_fonts = 1
endif

It's easier to know which hosts you have patched and it's not a really a problem if the list is not up to date.
