Question

我正在尝试转换一些us-ascii编码的xml文件变压器使用utf-8 / iso-8859-1可以正常工作，但不适用于us-ascii。我还尝试使用FileInputStream方法但不确定您是否在StreamResult部分指定了任何编码

这是我的代码：

    File xsl = new File("src/xsl/prism.xsl");
    String fname = file.getName();

    TransformerFactory factory = TransformerFactory.newInstance();
    Source xslt = new StreamSource(xsl);

    try{

        Transformer transformer = factory.newTransformer(xslt);
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
        transformer.setOutputProperty(OutputKeys.ENCODING, "us-ascii");
        Source text = new StreamSource(file.getCanonicalFile());

        System.out.println("Transformed "  + fname + "\n");
        transformer.transform(text, new StreamResult(new File(outPath + file.getName())));


    }catch (TransformerException | IOException e) {

        System.out.println("Error in: "+fname+"\n");
        e.printStackTrace();

    }

以下是抛出的异常：

变换器尝试加载源XML文档时发生错误。它尝试使用UTF-8编码读取它（如果没有XML声明或声明不包含编码属性，UTF-8是默认值。）

显然会抛出错误，因为源文件未在UTF-8中正确编码。

现在，任何以7位ASCII编码的文件也是有效的UTF-8。因此，源文档不能是7位ASCII文件。

3字节UTF-8序列xml转换异常的字节2无效
