Some debugging with gdb indicates that the codec is indeed writing the 'nd', but the final PyStringResize() (which allocates a new buffer and copies the data into that buffer) fails to copy the last two characters from the string or overwrites it with NULLs.

Looks like a pymalloc problem to me. Tim ?

It's a UTF-8 codec bug. The codec writes over the end of the buffer, then invokes resize. Resizing only copies the allocated bytes, hence the uninitialized bytes at the end.
