In this screenshot of my vimrc settings, I have installed the plugin vim-airline using vundle. After going through airlines docs, I found the set of lines to customise my airline.
The problem is the ones highlighted in red. The blue highlighted one works fine but the red one does not. The left one is same as right one. I tried using different Unicode symbols but does not work. Any workaround to this situation as this is troubling my OCD :P.
Thanks in advance.
