You did not use a fixed font! A patch means manually adding six additional characters to a font in certain places in formatted fonts in UTF format. If these characters are missing, you get the ugly blocks of notes you receive. You can either fix yourself using fontforge (not easy!), Or you can just download and install a previously fixed font from this page:

Installing a font on Windows is simple: right-click and select Install . Then you install it as usual in this _vimrc:
set guifont=Liberation_Mono_for_Powerline:h10
Linux.vimrc for completeness
set guifont=Liberation\ Mono\ for\ Powerline\ 10
Then for the airline
let g:airline_powerline_fonts = 1
or powerline
let g:Powerline_symbols = 'fancy'
Other settings are optional.
