UTF8输出，而不是ISO88591 java Linux

Question

应用程序（Java 1.6）在Linux平台上运行，我用ISO-8859-1编码创建了一个文件 像这样

 File localTempDir = new File(tempDir);
 String encoding = TextUtils.ISO_8859_1;

    try {
        String fileName = String.format(fileNameFormat, sdf.format(new Date()));
        tmpFile = File.createTempFile(fileName, "", localTempDir);
        log.info("Created file " + tmpFile.getAbsolutePath());

        OutputStreamWriter outputStreamWriter;

        if(StringUtils.isNotBlank(encoding)){
            outputStreamWriter = new OutputStreamWriter(new FileOutputStream(tmpFile), Charset.forName(encoding));
        }else{
            outputStreamWriter = new OutputStreamWriter(new FileOutputStream(tmpFile));
        }

        BufferedWriter out = new BufferedWriter(outputStreamWriter);
        out.write(content);

        log.debug("With content " + content);
        out.flush();
        out.close();
    } catch (Exception e) {
        log.error("Failed to create file", e);
    }
    return tmpFile;
}`

但仍然得到一个UTF8编码的文件。知道为什么吗

先简化。试试这个：

File localTempDir = new File(tempDir);
String encoding = "ISO-8859-1"; // "Cp1252" = Windows Latin 1

try {
    String fileName = String.format(fileNameFormat, sdf.format(new Date()));
    tmpFile = File.createTempFile(fileName, "", localTempDir);
    log.info("Created file " + tmpFile.getAbsolutePath());

    OutputStreamWriter outputStreamWriter;

    if (!encoding.isEmpty()) {
        outputStreamWriter = new OutputStreamWriter(new FileOutputStream(tmpFile), encoding);
    } else {
        outputStreamWriter = new OutputStreamWriter(new FileOutputStream(tmpFile));
    }

    PrintWriter out = new PrintWriter(new BufferedWriter(outputStreamWriter));
    try {
        out.print(content);

        log.debug("With content " + content);
    finally {
        out.close();
    }
} catch (Exception e) {
    log.error("Failed to create file", e);
}
return tmpFile;

}
