Java - 將xml文件從ISO-8859-2轉換為UTF-8

Question

我需要將文件從ISO-8859-2 charset轉換為UTF-8。

我的代碼是：

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));

但問題是，在轉換后，文件仍然是ISO-8859-2。

我究竟做錯了什么 ？

Answer 1

1. 使用“ISO-8859-2”Reader / Stream讀取xml
2. 使用xslt變換添加<?xml version=“1.0” encoding=“utf-8”?>標題
3. 使用用“UTF-8”編碼構造的Writer / Stream
