towctrans - wide-character transliteration
wint_t towctrans(wint_t wc, wctrans_t desc);
If wc is a wide character, the towctrans() function translates it according to the transliteration descriptor desc. If wc is WEOF, WEOF is returned.
desc must be a transliteration descriptor returned by the wctrans(3) function.
The towctrans() function returns the translated wide character, or WEOF if wc is WEOF.
The behavior of towctrans() depends on the LC_CTYPE category of the current locale.
