将传入字符串上的 unicode 表示形式转换为 UTF-8? [英] Convert unicode representations on incoming string to UTF-8?

问题描述

我正在读取一些已经转换为 html 样式 υ 代码的数据.

I'm reading some data that has already been converted to html style υ code.

我现在需要将其转换回 UTF-8 字符以供查看.不幸的是，我无法使用浏览器查看字符串.

I now need to convert this back to UTF-8 characters for viewing. Unfortunately I can't use a browser to view the string.

我已经阅读了有关 Java 转换的内容，似乎如果您有一个 \uxxxx 字符串，那么编译器会为您进行转换；但是这当然行不通，因为我想读取动态字符串.

I've read around about conversion in java and it seems if you have a string of \uxxxx then the compiler will convert for you; However that wont work of course because I want to read in dynamic strings.

这能做到吗?

非常感谢！丹

推荐答案

您需要使用:

String StringEscapeUtils.unescapeJava(String str)

来自 Apache 公共图书馆.

from the Apache Commons Library.

它将在输入字符串中找到\uxxxx 序列并将它们转换为普通的Java 字符串.

It will find \uxxxx sequences in the input string and convert them to a normal Java String.
