convert char * to wchar_t *

Question

I have a file.txt encoded in gbk, I read some bytes through ifstream::read and store them into a char buffer, then I want to print every word in the buffer in gbk.

I assume wchar_t is needed here, so I do it like this:

int main()
{
    ifstream ifs("./file.txt");
    char buf[256];
    ifs.read(buf, 255);

    wchar_t wbuf[256];
    mbstowcs( wbuf, buf, 255);
    for (int i = 0; i < wcslen(wbuf); i++)
        wprintf(L"%c ", wbuf[i]);

}

Am I doing it right? Or any better idea to do the job?

Thanks.

You need an external library such as `iconv` to convert GBK into something useful (such as WCHAR). — Kerrek SB, Aug 13 '12 at 19:18

Have you tried using the wide-char specializations? (ifstream and wifstream are template specializations of basic_ifstream over char and wchar_t respectively.)

wifstream wifs("./file.txt");
wifs.imbue(locale("zh_CN.GBK"));
wchar_t wbuf[256];
wifs.read(buf, 255);

+1, this is the standard way… although named locales aren't supported on all platforms. – Potatoswatter Jul 29 '12 at 07:08
