I want to know the answer to the following question:
What is the Russian back-transliteration from Encyclopædia Britannica?
All the background I'm provided with is that "Even in the Encyclopædia Britannica one can find "ostrov Khiuma", where "ostrov" means "island" in Russian and "Khiuma" is back-transliteration from Russian instead of "Hiiumaa" (Hiiumaa > Хийума(а) > Khiuma).". Is that enough to answer the question?
