Strings are immutable in Java, which means we cannot change aStringcharacter encoding. To achieve what we want,we need to copy the bytes of theStringand then create a new one with the desired encoding. First, we get theStringbytes, and then we create a new one using the retrieved bytes ...

关于这些特殊编码,官方一句说明: For the codecs listed below, the result in the “encoding” direction is always a byte string. The result of the “decoding” direction is listed as operand type in the table. encode的结果一定是一个byte的str,而decode的结果在表中operand一列。
So the encode is used to transform **the string to the byte sequence**. And when you call the encode function, you need to specify the encoding type, such asutf-8,gbk,gb2312, etc. And python will use the encoding type to transform every character in the string to the corresponding by...
