man ncurses
You must also define _XOPEN_SOURCE_EXTENDED when compiling for the
wide-character library to use the extended (wide-character) func‐
tions. The curses.h file which is installed for the wide-charac‐
ter library is designed to be compatible with the normal library's
header. Only the size of the WINDOW structure differs, and very
few applications require more than a pointer to WINDOWs. If the
headers are installed allowing overwrite, the wide-character
library's headers should be installed last, to allow applications
to be built using either library from the same set of headers.
man mvaddnwstr
int mvaddnwstr(int y, int x, const wchar_t *wstr, int n);
