They're still valid integers. It's just that someone might not know
how to work with them. Everyone has limits - I don't think repr()
would like to be fed Graham's Number, for instance, but we still say
that it accepts integers :)

Yeah. Either way, the problem isn't "be careful about Unicode
characters". One option has Unicode characters, the other doesn't, and
you need to know which one it is.

I just don't like people talking about "Unicode characters" being
somehow different from "normal text" or something, and being something
that you need to be careful of. It's not that there are some
characters that behave nicely, and then other ones ("Unicode" ones)
that don't.
