将我的应用程序打包为 JAR 后，希腊字符在生成的 XML 文件中显示得很奇怪
Greek characters are displayed weirdly in the produced XML file after packaging my application as JAR
我在 JDK 16 年开发了一个基于 dom4j 库的 Java 应用程序，它添加了一些特定的 XML 元素作为提供的 XML 文档。输入 XML 文档的某些元素，以及我的应用在输入文档中创建和添加的 XML 元素的某些子元素，包含希腊字符串作为内容。例如，这是输入 XML 文件的一个这样的元素：
<DecPlaHEA394>ΠΕΙΡΑΙΑΣ</DecPlaHEA394>
这是我创建并添加到输入文档的 XML 元素：
<VEHDET>
<FraNumVD1014>LATTCJCY7M1400121</FraNumVD1014>
<VehCC4006>124</VehCC4006>

每当我从 Eclipse 运行 我的应用程序时，输出 XML 中的任何希腊语内容都显示为纯希腊语文本，与输入 XML 文件中的完全一样。昨天，在使用 Maven 程序集插件将我的应用程序打包到包含所有依赖项的“uberjar”之后，我注意到，当我 运行 它通过从 Windows 终端执行提到的 JAR 时，所有希腊内容在输出 XML 文件中以 UTF-8 编码显示（我需要在此处将其添加为屏幕截图，以便理解我面临的问题）：
输入 XML 文件的编码是“utf-8”，但我注意在输出 XML 中使用相同的编码。通过将输入 XML 文件的 XML 内容复制到其中并添加提到的 XML 元素来生成输出 XML 的代码如下：

SAXReader reader = new SAXReader();
Document document = reader.read(urlOfInputXMLFile);
String encoding = document.getXMLEncoding();
// Get the root element:
Element root = document.getRootElement();
// For each different model: 1 to howManyModels
// - Find its respective GOOITEGDS: Find all the GOOITEGDS, store them in the list, and get them one at a time
// - Find its respective TAXADDELE100: Same way
// - Call writeVEHDATBlocksToXMLImportAndHomeUseCases() or writeVEHDATBlocksToXMLWarehousingCase() with the GOOITEGDS and the TAXADDELE100
// for the current model.
// Get the node GOOITEGDS (parent node of these nodes)
List<Element> gooIteGdsElemList = root.elements("GOOITEGDS");
if ((gooIteGdsElemList != null)) {
