Anything where you combine it with bytes has to result in bytes, or prepare for the combining operation to raise if the bytes contain any non-ASCII.
More helpfully, the Ascii object would raise *before* that - it would raise on construction if it had any non-ASCII in it. Combining an Ascii with a bytes results in a perfectly well-formed bytes; combining an Ascii with a unicode results in a perfectly well-formed unicode. But I'm not sure how (a) useful and (b) feasible this is. The only real use-case I know of is Path objects, and there may be similar tasks around numpy or pandas, but I don't know for sure. ChrisA
