So, you have to check every compiler and every compiler version to see
what the signedness of char is. That is not good in these days of
UTF-8.
Not really. You can usually write code that doesn't care whether
plain char is signed or unsigned. And if it matters, you can check
whether CHAR_MIN==0.
This evolved from systems like the PDP-11 where character values
ranged from 0 to 127, so the signedness of plain char didn't
matter much.
It's annoying that, in many implementations, UTF-8 strings can
contain elements with negative values (negative character values
rarely make sense), but in practice it doesn't cause many problems.
IMHO it would be cleaner to require plain char to be unsigned,
but I don't see that happening.
