Czechia wins official backing as shortened name for Czech Republic

The “Czech Repubic” => “Czechia”. Just don’t confuse it with Chechnya — the Czechs are sensitive about that. (Actually, not so much sensitive, they probably just think you’re uneducated if you don’t know the difference.)

This name has been in use already for years by many other Slavic nations (e.g. Russian Чехия), so they didn’t just pull it out of a hat.
