You consider one very simple case (isprint/iscontrol only) and think
that it is a proof. What you can say about ispunct() f.e.?
It is clearly differ into 8859-1 and 8859-5 f.e., islower/isupper differs
too. tolower/toupper differs too. Even isalpha differs.

Well, isspace differs too.

No it is different problem. By setting LANG for something != 8859-1
(for programs that understands it) I assume that programs which
not understands it still works right.
If they are strict ASCII, I automatically protected from any
unwanted effects. If they are 8859-1 I need to classify
various unwanted effects for each != 8859-1 charset as
'default undefined behaviour'.
