What does this board think the best way to set up a cinematic PC who knows vast numbers of languages, but only those they could reasonably know.

Example: A Cliffhangers scholar who studied at Harvard, Oxford, Cambridge, and Heidelburg, and knows every language recorded at those Universities by 1925. But, if Vulcans exist in this universe, being unknown to Western scholarship in 1925, he doesn't know their language. Similarly isolated Amazonian tribes, inhabitants of "lost worlds," newly awakened Atlanteans, all speak languages he doesn't know....yet.
