or changing the behavior or dtype 'S', but yes, the other thread.

But the OP's problem was not that s/he got bytes, but that the content was
wrong -- he got the repr of bytes in a py3 string.

a key missing feature -- and I doubt it does utf-8 right, either.

as mentioned in my earlier mail this works for ascii:

thanks -- I wasn't sure what astype would do for that. and what are you
getting then, unicode or ascii?
