This question already has an answer here:
I thought that the droid from Star Wars Rebels spoke in binary, but somehow Hera and Ezra are able to understand and interpret for it. It made sense for C3PO to understand R2 because they're both machines, and I always thought when a human character understood R2 it was because they had a console in front of them (I could be wrong, but I don't remember any instances where this wasn't the case). This doesn't seem to be the case for Chopper though. So, is Chopper not speaking in a binary encoding? Or is it somehow possible for humans to interpret binary in the Star Wars Universe?
