The first 256 unicode code points, which happen to coincide with latin1.

Changing the null chopping and preserving backward compat would
require yet another new dtype. This would then mean that the 'S' dtype
would become pretty much deprecated on Py3.

Forcing everyone to re-do their Python 3 ports would be somewhat
cleaner. However, this train may have left a couple of years ago.
