Printf's handling of unicode is inconsistent in other ways, too. I suspect that

Ok - so your native environment locale is ``UTF-8''.
% cat localized.c
Why that program is named ``localized'' if...

int main() {
wprintf (L"'%4ls'\n", L"äöü");
... you are using "C" locale for LC_CTYPE? Behavior entirely
unsurprising: there is no conversion from L"äöü" using "C" LC_CTYPE.

setlocale(LC_ALL, "");
... you are using native environment locale (``UTF-8'') for LC_CTYPE?
Behavior entirely unsurprising: there is conversion from L"äöü" using
"UTF-8" LC_CTYPE.
