Yeah, was aware of that possibility; I guess I should have made a point about the disctinction between symbols vs "possible sound combinations" (my words). And even "possible sound combinations" can be further limited to "actually used sound combinations" as mentioned in the answer on that SO link.

So, in terms of "possible sound combinations" I think Japanese would likely be on the lower side given that the number of sounds are also pretty low. Alright, thank you for that reply; the point in the original post I replied to makes more sense to me now.
