一个GBK转UTF8的问题，求教高手

[kllll1119]

#include <iostream>
#include <string>
#include <windows.h>

using namespace std;


string GBKToUTF8(const string& strGBK)
{
	string strOutUTF8 = "";
	WCHAR * str1;
	int n = MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, NULL, 0);
	str1 = new WCHAR[n];
	MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, str1, n);
	n = WideCharToMultiByte(CP_UTF8, 0, str1, -1, NULL, 0, NULL, NULL);
	char * str2 = new char[n];
	WideCharToMultiByte(CP_UTF8, 0, str1, -1, str2, n, NULL, NULL);
	strOutUTF8 = str2;
	delete[]str1;
	str1 = NULL;
	delete[]str2;
	str2 = NULL;
	return strOutUTF8;
}

void main()
{
	cout << GBKToUTF8("队<") << endl;
	cout << GBKToUTF8("队") << endl;

	string str = GBKToUTF8("队");
	cout << str+"<" << endl;
} 

运行结果：
//打不来那个字，用星号代替
*?
*
*？

感觉那个字符和'<' 连在一起就变问号了，这个怎么处理啊，想正常显示'<'

用iconv吧，参考下面代码：

#include <iconv.h>
#pragma comment(lib,"iconv.lib")
 
int code_convert(char *from_charset,char *to_charset,const char *inbuf, size_t inlen,char *outbuf, size_t outlen)
{
         iconv_t cd;
         const char **pin = &inbuf;
         char **pout = &outbuf;
 
         cd = iconv_open(to_charset,from_charset);
         if (cd==0) return -1;
         memset(outbuf,0,outlen);
         if (iconv(cd, pin, &inlen,pout, &outlen)==-1) return -1;
         iconv_close(cd);
         return 0;
}
 
/* UTF-8 to GBK  */
int u2g(const char *inbuf, size_t inlen, char *outbuf, size_t outlen)
{
         return code_convert("UTF-8","GBK",inbuf,inlen,outbuf,outlen);
}
 
/* GBK to UTF-8 */
int g2u(const char *inbuf, size_t inlen, char *outbuf, size_t outlen)
{
         return code_convert("GBK", "UTF-8", inbuf, inlen, outbuf, outlen);
}
