Adding Unicode/UTF8 chars to a ncurses display in C

Question

I\'m attempting to add wchar_t Unicode characters to an ncurses display in C.

I have an array:

wchar_t characters[]={L\'\\uE030\', L\'\\uE029\'}; //          


        

Answer 1

cchar_t is defined as:

typedef struct {
    attr_t  attr;
    wchar_t chars[CCHARW_MAX];
} cchar_t;

so you might try:

int add_wchar(int c)
{
    cchar_t t = {
        0, // .attr
        {c, 0} // not sure how .chars works, so best guess
    };
    return add_wch(t);
}

not at all tested, but should work.

Answer 2

This is not 2 characters:

wchar_t characters[]={L"\uE030", L"\uE029"};

You're trying to initialize wchar_t (integer) values with pointers, which should result in an error from the compiler. Either use:

wchar_t characters[]={L'\uE030', L'\uE029'};

or

wchar_t characters[]=L"\uE030\uE029";

Answer 3

Did you define _XOPEN_SOURCE_EXTENDED before including the ncurses header?

Answer 4

The wide character support is handled by ncursesw. Depending on your distro, ncurses may or may not point there (seemingly not in yours).

Try using -lncursesw instead of -lncurses.

Also, for the locale, try calling setlocale(LC_ALL, "")
