默认编码的字节数组转为 ISO-8859-1 编码的字节数组

Question

i have a byte array having default encoding.
i want to change that byte array to byte array of "ISO-8859-1" encoding.
How to do this..? Please help me

Answer 1

byte[] isoBytes = new String(curBytes).getBytes("ISO-8859-1");

但是请注意，如果默认编码已经“丢失”了一些字符，则无法通过这种方式恢复它们。

Answer 2

String str = new String(currentByteArray);
byte[] newByteArray = str.getBytes("ISO-8859-1");

Answer 3

OK, so you have a String transformed to a byte array using the default platform encoding (whatever it is. And you want to transform this string to a byte array using ISO-8859-1.

The first step is thus to transform the byte array to a String:

String s = new String(bytes); // default encoding used here

and then to transform it back to a byte array:

byte[] iso88591Bytes = s.getBytes("ISO-8859-1");
