在Java中检测（或最好的猜测）传入字符串编码 [英] Detect (or best guess of) incoming string encoding in Java

问题描述

我想知道是否有已知的方法来检测（或给出最好的猜测）Java中特定字符串的编码。

我知道你总是需要一些额外的元数据来告诉编码是什么，还有最佳做法等，但是我遇到的情况我需要给出最佳的近似值。

一个解决方案 - 或指针 - 在UTF-8和UTF-16之间进行编程区分也是受欢迎的。

解决方案

utf-8编码应该很容易验证：

UTF-8字符串可以通过简单的启发式算法相当可靠地识别。

I was wondering if there are known methods to detect (or give a best guess of) the encoding of a particular string in Java.

I know that you always need some additional meta-data to tell what the encoding is, and there are best practices etc., but the situation I'm in, I need to give the best approximation.

A solution -- or a pointer -- to programatically distinguishing between UTF-8 and UTF-16 is also welcome.

解决方案

The utf-8 encoding should be easy to verify:

UTF-8 strings can be fairly reliably recognized as such by a simple heuristic algorithm. from wikipedia
