[C++ VC] iconv库的使用

GB2312字符串转换为UTF-8的字符串，代码如下：

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


int main(void)
{
    unsigned char *src = "魅影追击和歌姬"; /* 需转换的字串 */
    unsigned char dst[256] = {0}; /* 转换后的内容 */
    unsigned char buf[1024] = {0}; /* 格式化转换后的字串 */
    size_t src_len = strlen(src);
    size_t dst_len = sizeof(dst);
    unsigned char *in = src;
    unsigned char *out = dst;
    
    iconv_t cd;
    int i;  
    int j;  
    
    cd = iconv_open("UTF-8", "GB2312"); /* 将GB2312字符集转换为UTF-8字符集 */
    if ((iconv_t)-1 == cd)
    {
        return -1;
    }

    printf("src: %s\n", src);
    iconv(cd, &in, &src_len, &out, &dst_len); /* 执行转换 */

    /* 以下将转换后的内容格式化为: %XX%XX...形式的字串 */
    printf("dst: ");
    j = 0;  
    for (i = 0; i < strlen(dst); i++)
    {
        printf("%.2X ", dst[i]);
        buf[j++] = ''%'';
        snprintf(buf + j, 3, "%.2X", dst[i]);
        j += 2; 
    }
    printf("\n");
    printf("buf: %s\n", buf);
    
    iconv_close(cd); /* 执行清理 */
    return 0;
}
