towlower manual

towlower - convert a wide character to lowercase

 The  towlower()  function  is  the  wide-character  equivalent  of  the
 tolower(3) function.  If wc is an uppercase wide character,  and  there
 exists  a  lowercase  equivalent  in the current locale, it returns the
 lowercase equivalent of  wc.   In  all  other  cases,  `wc`  is  returned
 unchanged.

 The towlower_l() function performs the same task, but performs the con-
 version based on the character type information in the locale specified
 by  locale.  The behavior of towlower_l() is undefined if locale is the
 special locale object `LC_GLOBAL_LOCALE` (see duplocale(3)) or is  not  a
 valid locale object handle.

 The argument wc must be representable as a wchar_t and be a valid char-
 acter in the locale or be the value `WEOF`.

Return Value

If wc was convertible to lowercase, towlower() returns its lowercase equivalent.
Otherwise, it returns wc.

Notes

The behavior of towlower() depends on the LC_CTYPE category of the current locale.

These functions are not very appropriate for dealing with Unicode characters, because Unicode knows about three cases: upper, lower and title case.

The towlower_l() function not implemented is libwchar2.
