This is new code:

#include <iconv.h>
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void print_buf(char* buf, size_t len)
{
        size_t i;
        for (i = 0; i < len; ++i) {
                printf("%02X ", (unsigned char)buf[i]);
        }
        printf("\n");
}

int main(int argc, char** argv)
{
        char s[] = "早見純";
        print_buf(s, sizeof(s));
        iconv_t cd = iconv_open("GB18030", "UTF-8");
        if (cd <= 0 ) {
                printf("iconv_open fail\n");
                return 0;
        }
        size_t inbytesleft = sizeof(s) - 1;
        char dst[6 * sizeof(s)] = { 0 };
        size_t outbytesleft = sizeof(dst) - 1;
        char* inbuf = s;
        char* outbuf = dst;

        if (iconv(cd, &inbuf, &inbytesleft, &outbuf, &outbytesleft) ==
(size_t)-1) {
                printf("iconv fail: %d\n", errno);
        }
        iconv_close(cd);
        size_t n = strlen(dst);
        printf("inbytesleft: %u, outbytesleft: %u, dst len: %u\n", inbytesleft,
outbytesleft, n);
        print_buf(dst, n);
        return 0;
}

array s contents is :
E6 97 A9 E8 A6 8B E7 B4 94 EE A0 97 00
