So a question popped up on my sidebar asking about Binary, which is apparently the name given to robot speech in Star Wars (specifically, the very non-binary language used by R2-D2 and similar astromechs). The name was clearly created by someone who had no clue about computers, communication protocols, etc., and I wouldn't put it past the film industry to use such a ridiculously inaccurate term just because it's vaguely computer-sounding. But I don't remember ever hearing of The Binary Language in any canon source. I know there are references to binary languages, but all the ones I can find are references to specific droids and their specific languages which aren't actually heard on-screen.
Is there any canon source that refers to a non-binary droid language as Binary?
