1、如何创建unicode 项目
选择“Project->Setting”菜单
(1)选 Win32 Unicode Debug ：
切换到“c/C++ ” Tab页 从下拉列表框中选择 “Preprocessor” ,去掉_MBCS，添加UNICODE,_UNICODE(注意逗号隔开） ，如果是MFC程序，还要在
link中，Category选output,将Entry-Point Symbol设为wWinMainCRTStartup
2、unicode码格式存放的16进制数据显示成可见的字符
例子： 如何在电脑上显示出 0x6211 0x4eec ？
代码：
//我们： 我们 0x6211 0x4eec
TCHAR MyWchar[128];
//WCHAR MyWchar[128];
memset(MyWchar, 0, sizeof(MyWchar));
MyWchar[0] = 0x6211;
MyWchar[1] = 0x4eec;
MyWchar[2] = 25105;
MyWchar[3] = 20204;
int a = ((6*16 + 2)*16 + 1)*16 + 1;
MessageBox(MyWchar);
3、Ascii码格式存放的16进制数据显示成可见的字符
同2,
具体代码：
// ab: 87,98
char str[20] = {97,98,0};
MessageBox(str);
转换函数：
/**

例如:"62114eec"-> "我们"
