curses (or ncurses) output of UTF-8 test with addchstr()

In curses (or ncurses), how can I output a UTF-8 encoded char* by using
addchstr() (or any other function taking a 'chtype' as argument)?

This (obviously) won't work:

(It's C99.)


const char* utf8Str = "Some UTF-8 text here";
chtype cursesStr[SOME_SIZE];

for (size_t i = 0; i < strlen(utf8Str); ++i) {
cursesStr[i] = utf8Str[i] | A_CURSES_ATTRIBUTE_WE_WANT;
}
cursesStr[i] = 0;

addchstr(cursesStr);


I guess I would have to combine every UTF-8 multibyte sequence in
utf8Str into a single chtype and store that in cursesStr.  I can't seem
to succeed in it.  Is it even possible to use addchstr() and friends for
UTF-8 strings?  Or would I have to convert from UTF-8 to some other
Unicode encoding?  If yes, which one?  If no, what are my options?

In ncurses, you can (assuming your locale is already using a UTF-8 encoding)
use addstr.  More generally (or to pass along an attribute), you would use
setcchar, as illustrated in ncurse's test/view.c
