any of those will
very likely yield a blank page when you first try it since it'll have
to render the world at zoom 2 for that language (unless someone had it
rendered already):

But some of them are already up:

"Demokratische Republik Kongo", also "Central African Republic" should
be "Zentralafrikanische Republik".
