But would it be better if this gave a different result?

	signed char n = '\n';
	std::cout << "Hello world" << n;

(or s/signed/unsigned/)

That seems just as peculiar, though I guess I could go for "unsigned
char" being different; actually it would be quite convenient for my code
if that displayed as hex.
