So is twitter sending Shift_JIS encoded responses back? That seems unlikely given it seems easier to engineer accepting anything but always send utf-8 back, but definitely interesting if that's the case.

Also, why downvote? Even if was largely wrong, the discussion engendered was a net positive to HN.

I think twitter generates answers based on the client's Accept-Encoding header. Well, I assumed that. Come to think of it though, it does seem unlikely and you make a good point.

I did not downvote, or if I did I did not mean to, op's comment certainly did not deserve it.
