This version passes the first test (after fixing the format, as you
noted), but it looks like get_properties is returning pairs of
bytestrings.

I don't _think_ that's what we want. We had some discussion before and
decided that it was reasonable to only support utf-8 properties, so
converting to strings should be OK?
