+## Flags representation in client side
+
+Some operating systems and web browsers may not be able to represent unicode flags due political reasons. I recommend to use the libraries like [country-flag-emoji-polyfill](https://github.com/talkjs/country-flag-emoji-polyfill) in order to provide a graphical representation of the flags in the client side.
