I wish cmsortkey didn't take input in binary; I suspect what's happening here is that some layer is trying to interpret the binary characters as UTF-8 and thereby screwing them up.

I think the real fix here will be deprecating cmstartsortkey and cmendsortkey in favor of something like cmstarthexsortkey and cmendhexsortkey that take the input hex-encoded.
