I'm not saying that at all. What I'm saying is that I'm using Python3
strings as holders for bytes. Since every byte is a valid Unicode code
point, a Python3 string can hold any sequence of bytes.
Couldn't you use bytes objects everywhere for the same purpose?
Yes and no.
Yes, but it would be ugly as hell and would involve changing a large
percentage of the source code.
No, as a large number of Python3 facilities require str objects as
arguments. Consider urllib.request.urlopen(), for example, which
requires a URL to be an str object.
