Well, if you insist on the classical latin alphabet then I'm affraid English doesn't even qualify: it doesn't provide for those funny "J" and "U" foreing squiggles English uses.  -)  —  (talk) 
(e/c)@Jimmy: No, it's actually very plausible that Wałęsa did exactly that; almost certainly for the same reason I did.  In fact, if you can find a source that says he did I would support titling the article that way without reservation.  Can you argue that "Moscow" isn't a different name from "Moskva / Москва"?  I see no reason to posit that this is a random exception.  —  (talk)
