TOWLOWER (3)
convert a wide character to lowercase
SYNOPSIS
#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
lowercase. 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.

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