Just the other day I learnt about the hairy heart emoji in Android 4.4, which was actually misinterpreted from a black-and-white hatched heart in unicode that used the dots to indicate yellow, per this wiki article.
As someone who writes about heraldry, I'm happy to see this here. I'm a little surprised, though. What about this is interesting for the Hacker News crowd?
