I guess you have a UCS-2 python binary, and that's why you're getting this result. Try also `len(u'\U0001d200')` - I bet it returns 2.

`_convert_positions` was supposed to take UCS2 into account (with the lines that begin with `emit_`). If you can figure out what the problem is, that would be great.
