Language fallback

I completely agree with Srdjan m. Just to add up, Bosnian, Croatian, Montenegrin, and Serbian are synonymous names for Serbo-Croatian, a name used by linguistic academia world-wide with the exception of scholars in each of the Serbo-Croatian-speaking countries, at least a significant number of them, who cannot reach an agreement regarding the name of their standard language. Slovene has a less mutual intelligibility with Serbo-Croatian and is always translated in Serbo-Croatian-speaking media (TV and radio), so it is better to stick to the Serbo-Croatian varieties or to recur to English.
