tinyxml读取中文时显示乱码的解决方法

1、tinyxml解析器是一个很好用的，乱码是由于GB2312与UTF8之间转换不当造成的,tinyxml在处理UTF8本身没有问题。

2、网上很多人提供的方法是进行GB2312与UTF8之间的转换

经测试时有效的

转换代码为：

#include <Windows.h>

#define U   (CUtf8String)
#define W   (CGb2312String)

class CUtf8String
{
public:
	inline CUtf8String(const char* gb2312)
	{
		m_bIsConst = true;
#ifdef TEST_TYPE_MAP
		if (m[gb2312])
		{
			m_utf8 = m[gb2312];
			return ;
		}
#endif
		int buffLen = 0;
		WCHAR wbuff[5120];
		MultiByteToWideChar(CP_ACP, 0, gb2312, -1, wbuff, 5120);
		buffLen = WideCharToMultiByte(CP_UTF8, 0, wbuff, -1, NULL, 0, 0, 0);
		m_utf8 = new char[buffLen+1];
		WideCharToMultiByte(CP_UTF8, 0, wbuff, -1, (LPSTR)m_utf8, buffLen, 0, 0);
#ifdef TEST_TYPE_MAP
		m[gb2312] = m_utf8;
#endif
	}

	inline CUtf8String(char* gb2312)

例子：

 printf("%s", U"你好中国!");
