VC 判断CString字符串中各位是数字，大小写字母，符号，汉字。(UNICODE和ANSI)

其中日文、中文简体、繁体没法分开，编码都是在一起的。

// UNICODE字符集 CString str =  L"0123abc雲中鶴+-*ほニホ";    CString shuzi,biaodianfuhao,hanzi,daxiezimu,xiaoxiezimu;    for (int i = 0 ; i <str.GetLength();i++)    {        int unicode = (int)str.GetAt(i);        if (unicode <= "9" && unicode >= "0")        {            shuzi += str.GetAt(i);        }        else if (unicode <= "z" && unicode >= "a")        {            xiaoxiezimu += str.GetAt(i);        }        else if (unicode <= "Z" && unicode >= "A")        {            daxiezimu += str.GetAt(i);        }        else if (unicode > 255)        {            hanzi += str.GetAt(i);        }        else        {            biaodianfuhao += str.GetAt(i);        }    }
