Java - 将 xml 文件从 ISO-8859-2 转换为 UTF-8

Question

我需要将文件从 ISO-8859-2 字符集转换为 UTF-8。

我的代码是:

DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
        Document doc = builder.parse(file);


        DOMSource domSource = new DOMSource(doc);

        String fileName2 = UUID.randomUUID().toString() + "222";
        Writer out = new OutputStreamWriter(new FileOutputStream("/Users/user/Kohana/" + fileName2 + ".xml"), "UTF8");

        Transformer transformer = TransformerFactory.newInstance().newTransformer();
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
        transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
        transformer.transform(domSource, new StreamResult(out));

但问题是，转换后，文件仍然是ISO-8859-2。

我做错了什么？

Answer 1

1. 使用“ISO-8859-2”读取器/流读取 xml
2. 使用xslt转换添加<?xml version=“1.0” encoding=“utf-8”?>标题
3. 使用以“UTF-8”编码构建的 Writer/Stream
