As Syria changes its flag, a look into Unicode's emoji politics (karlsnotes.com)
For years, tribes have used visual symbols to identify themselves and unite people behind shared values. This practice began with painted symbols and evolved to include flags following the invention of silk.

With the rise of the internet, flags naturally found their way online in the form of emojis, continuing their role as powerful identifiers in the digital age.

Is Android Unicode Yet? (shkspr.mobi)
