Sure. Technically, ASCII might include \0 (depending on definition),
but that is ruled out as a character in Python source code, anyway.

So: "must be an ASCII character" is just as clear, and much shorter.

I guess Jason associated "ASCII character" with "single byte",
so it can't be simultaneously both ASCII and Unicode, hence he
chose the more elaborate wording.  Of course, if one views ASCII
as a character set (rather than an coded character set), a Unicode
character may or may not simultaneously be an ASCII character.
