Gem for displaying international postal addresses?

Is there a Gem that can be utilized for displaying postal addresses in
the format specific to their destination country or region?

Basically, a Gem that programatically does what this site advises?

Anything similar?

Thanks!

Looks like a great start. Thank you!
