关于CString的一个巨奇怪的问题，哪位高手给指点一下下

[Eason]

我在使用CString的成员函数Find（）时发生了这样的奇怪现象:
字符串中存在大于127的字符，用Find()查找时有些字符查找不到。
比如，unsigned char a=255，这个a就可以查到
但是如果将a的值赋为240就查不到了。

这是什么原因啊，请给我指点一下，多谢

快以UNICODE方式编译吧

这样啊

同意prog_st(st)！

两种不同的字符定义模式……

使用UNICODE 吧！

CString 还有个问题，当你从某个汉字的第二个字节开始查找时，也是找不到的！
例如： CString str = _T("我是豆芽菜！");
str.Find(_T("豆芽菜"),1);他是找不到的！
因为CString 支持双字符集（UNICODE）和宽字符集（multibyte character），
在宽字符下，一个字符串可以即有ASCII字符（一个字节），又有汉字字符（双字节）。

[prog_st]

CString is based on the TCHAR data type. If the symbol _UNICODE is defined for your program, TCHAR is defined as type wchar_t, a 16-bit character type; otherwise, it is defined as char, the normal 8-bit character type. Under Unicode, then, CString objects are composed of 16-bit characters. Without Unicode, they are composed of 8-bit char type.

When not using _UNICODE, CString is enabled for multibyte character sets (MBCS, also known as double-byte character sets, DBCS). Note that for MBCS strings, CString still counts, returns, and manipulates strings based on 8-bit characters, and your application must interpret MBCS lead and trail bytes itself.

当作汉字的首字节来处理（>128）,说已查不到，
