有时候，根据程序的需要，可能会添加中文字体，但是程序在编码的时候可以能会出现乱码，那么这么处理呢，看如下代码：

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

#ifdef WIN32
#define UTEXT(str) GBKToUTF8(str)
#else
#define UTEXT(str) str
#endif

#ifdef WIN32
#include "platform/third_party/win32/iconv/iconv.h"

static char g_GBKConvUTF8Buf[5000] = {0};
const char* GBKToUTF8(const char *strChar)
{

    iconv_t iconvH;
    iconvH = iconv_open("utf-8","gb2312");
    if (iconvH == 0)
    {
        return NULL;
    }
    size_t strLength = strlen(strChar);
    size_t outLength = strLength<<2;
    size_t copyLength = outLength;
    memset(g_GBKConvUTF8Buf,5000);

    char* outbuf = (char*) malloc(outLength);
    char* pBuff = outbuf;
    memset( outbuf,outLength);

    if (-1 == iconv(iconvH,&strChar,&strLength,&outbuf,&outLength))
    {
        iconv_close(iconvH);
        return NULL;
    }
    memcpy(g_GBKConvUTF8Buf,pBuff,copyLength);
    free(pBuff);
    iconv_close(iconvH);
    return g_GBKConvUTF8Buf;
}
#endif

上面是汉字转换，有可能出先连接出问题的情况，那是程序所用到的iconv的lib没用添加进去，你只需要在你的工程--属性--连接--输入--添加依赖项--libiconv.lib(添加这个lib文件就可以了)
