将字符串编码为 UTF-8 [英] Encode String to UTF-8

问题描述

我有一个带有ñ"字符的字符串，但我遇到了一些问题.我需要将此字符串编码为 UTF-8 编码.我已经用这种方法试过了，还是不行:

I have a String with a "ñ" character and I have some problems with it. I need to encode this String to UTF-8 encoding. I have tried it by this way, but it doesn't work:

byte ptext[] = myString.getBytes();
String value = new String(ptext, "UTF-8");

如何将该字符串编码为 utf-8?

How do I encode that string to utf-8?

推荐答案

String Java 中的对象使用无法修改的 UTF-16 编码.

String objects in Java use the UTF-16 encoding that can't be modified.

唯一可以有不同编码的是byte[].因此，如果您需要 UTF-8 数据，那么您需要一个 byte[].如果您有一个包含意外数据的 String，那么问题出在更早的地方，错误地将一些二进制数据转换为 String(即它使用了错误的编码).

The only thing that can have a different encoding is a byte[]. So if you need UTF-8 data, then you need a byte[]. If you have a String that contains unexpected data, then the problem is at some earlier place that incorrectly converted some binary data to a String (i.e. it was using the wrong encoding).
