DESCRIPTION

14       The  towupper()  function is the wide-character equivalent of the toup‐
15       per() function. If wc is a wide character, it is  converted  to  upper‐
16       case.  Characters which do not have case are returned unchanged.  If wc
17       is WEOF, WEOF is returned.
18

RETURN VALUE

21       if wc is WEOF.

NOTES

30       The  behaviour  of  towupper()  depends on the LC_CTYPE category of the
31       current locale.
32
33       This function is not very appropriate for dealing with Unicode  charac‐
34       ters,  because  Unicode knows about three cases: upper, lower and title
35       case.
