Naturally.  UTF-8 is a multibyte character encoding; ASCII is strictly
single byte (using only seven bits).

Which is ASCII code 34 (0x22)

Again, looks the same as ASCII code 34.

And this is way outside the range of any 7-bit encoding, (it needs
fourteen bits plus UTF-8 encoding overhead spreading it across three
bytes), so has no ASCII representation.

I don't disagree.  However, Anthony clearly *is* confused, for he claims
to refer to ASCII output on UTF-8 devices.  It may seem pedantic, but a
confusingly expressed objective must perpetuate confusion.  While ASCII
may be a proper subset of UTF-8, it is a limited subset: it offers only
two choices for representation of quotes, viz. code 34 (double quote)
and code 39 (single quote or apostrophe).
