*Oppose. BGN/PCGN lists "Kharkiv" as an "approved" variant in the context of Ukraine, and that's good enough for me. The majority of "Kharkov" spellings in the results are pre-independence (i.e., used in the Russian/Soviet contexts). For Kiev/Odessa, the BGN/PCGN lists the "Kiev" spelling as "conventional" and the "Odessa" spelling as "approved", so there is no contradiction on that front either.— • ; March 19, 2014; 13:17 (UTC)
