I just downloaded and installed IDEA 2017.1 public beta and enabled Font Ligatures. It's actually pretty nice to get an UTF-8 arrow instead of just -> etc. I tried in 2016.03.4 but it's horribly slow. JetBrains will start to bundle their own JDK build with IDEA soon because they have done some performance improvements specifically dealing with fonts (and probably other things to speed up IDEA)
