my fonts are not displayed properly

[gkamendje]

I am running Centos7 and I have installed the fonts as recommended. However, using Vim Airline, the fonts are not displayed properly (see the attached screenshot). Not sure if this is a Gvim issue or if it is a fonts issue. I have it working properly on a Ubuntu machine as well as on a RedHat 7 machine. Not sure what I am doing wrong here.
