tinyxml读取中文时显示乱码的解决方法

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。

这里是网上找的一个经测试可以用的转换方法： printf("%s", U("中文汉字"));  即可

代码如下：

#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)
{
m_bIsConst = false;
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);
}

inline ~CUtf8String()
{
#ifndef TEST_TYPE_MAP
if (m_utf8)
{
delete m_utf8;
m_utf8 = 0;
}
#else
if (!m_bIsConst)
{
if (m_utf8)
{
delete m_utf8;
m_utf8 = 0;
}
}
#endif
}

inline operator char*()
{
return (char*)m_utf8;
}
private:
const char* m_utf8;
bool m_bIsConst;
#ifdef TEST_TYPE_MAP
static strmap m;
#endif
};

class CGb2312String
{
public:
inline CGb2312String(const char* utf8)
{
#ifdef TEST_TYPE_MAP
if (m[utf8])
{
m_gb2312 = 0;
m_gb2312 = m[utf8];
}
#endif
int buffLen = 0;
WCHAR wbuff[5120];
MultiByteToWideChar(CP_UTF8, 0, utf8, -1, wbuff, 5120);
buffLen = WideCharToMultiByte(CP_ACP, 0, wbuff, -1, NULL, 0, 0, 0);
m_gb2312 = new char[buffLen+1];
WideCharToMultiByte(CP_ACP, 0, wbuff, -1, (LPSTR)m_gb2312, buffLen, 0, 0);
#ifdef TEST_TYPE_MAP
m[utf8] = m_gb2312;
#endif
}

inline CGb2312String(char* utf8)
{
#ifdef TEST_TYPE_MAP
if (m[utf8])
{
m_gb2312 = 0;
m_gb2312 = m[utf8];
}
#endif
int buffLen = 0;
WCHAR wbuff[5120];
MultiByteToWideChar(CP_UTF8, 0, utf8, -1, wbuff, 5120);

m_gb2312 = new char[buffLen+1];
WideCharToMultiByte(CP_ACP, 0, wbuff, -1, (LPSTR)m_gb2312, buffLen, 0, 0);
#ifdef TEST_TYPE_MAP
m[utf8] = m_gb2312;
#endif
}

inline ~CGb2312String()
{
#ifndef TEST_TYPE_MAP
if (m_gb2312)
{
delete m_gb2312;
m_gb2312 = 0;
}
#endif
}

inline operator char*()
{
return (char*)m_gb2312;
}
private:
const char* m_gb2312;
#ifdef TEST_TYPE_MAP
static strmap m;
#endif
};
