#include <wctype.h>
wint_t towlower(wint_t wc);
DESCRIPTION
The towlower() function is the wide-character equivalent of the
tolower() function. If wc is a wide character, it is converted to low‐
ercase. Characters which do not have case are returned unchanged. If
wc is WEOF, WEOF is returned.
RETURN VALUE
The towlower() function returns the lowercase equivalent of wc, or WEOF
if wc is WEOF.

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