The previous article mentioned the generation of garbled code: http://blog.csdn.net/xieyuooo/article/details/6919007 The main reason is that the encoding and decoding methods are different. Sometimes, if we know the encoding method, decoding will naturally be very helpful, for example, the output contenttype will tell the browser what encoding format the output content is, otherwise the browser will use the current default character set encoding for p
