想用printf输出一个CString，有那么难吗

C/C++ code

    CString a = "test";    printf("%s\n", a);    printf("%s\n", a.GetBuffer());    printf("%s\n", a.GetBuffer(0));    printf("%s\n", a.GetBuffer(-1));

上述代码统一输出t,我想要输出一个test，居然怎么弄也弄不出来。

崩溃一个。

　If you use the pointer returned by GetBuffer to change the string contents, you must call ReleaseBuffer before using any other CString methods.

CString是unicode编码 
用 %S 试试
