>>We have presented evidence and arguments that huh?, or more precisely a short questioning interjection with the function of other-initiation of repair, is a universal word likely to be attested in similar form in all natural spoken languages

Since they used word "likely", then the whole article does not mean, that huh applies to every language. They also used "more precisely a short questioning interjection with the function of other-initiation of repair" - and that is more closer to truth, as such questioning interjection might be present in all languages. But it hardly represents topic of huh.

Only because of logic used in conclusion, I can dare to say with absolute truth that: "Earth is flat, or more precisely - it is not round as ball". You can just marvel when scientists became lawyers and when science died because of that type of language.

PS With exception to English, other 2 languages that I use as native user do not have any equivalent of huh? at all. Unless it is what?, as a shortened form of question - what did you said?, but it is hardly a candidate to huh? unless we are really stretching the argument to include everything else. With that argumentation we can stretch even mouse onto a elephant.
