font mapping broken

[shibumi]

Hello,
The last stable commit was fcfef52 every commit after this is broken due to font mapping issues.
When I apply any other commit after this my zsh powerline seems broken.

Screenshots:

Everything fine:

Broken:

I have no idea if this is the fault of zsh-theme-powerlevel9k or of awesome-terminal-fonts.

And the devicon font mapping seems wrong also: (doesn't matter with which commit):

ryanoasis/vim-devicons#173

I think that the explanation is in Powerlevel9k/powerlevel9k#429 they are referring to codepoints instead of using font maps and this is a problem. Codepoints are simpler but since icon fonts use the private area codepoints have no meaning but the one given by the font author, the author can remove, rename, move a glyph because there's no standard to refer to, so I think font maps are the way to go

Moreover most of the icon fonts have css files that does the same job
