关于openoffice转换pdf中txt乱码的问题

什么文件类型都好使，docx，doc，ppt，xls，xlsx，就踏马txt不行，各种乱码  
**气得我直接把txt统一转换成utf-8格式了，**  
看源码这个`import org.jodconverter.DocumentConverter;`里面写的没有设置编码类型的代码，也没法设置，找一下午找不见

@Autowired
        private DocumentConverter converter;

EncodingDetect这个类是我的检测文件编码的类

if("txt".equals(fileType)){ 
                String substring = UUID.randomUUID().toString().substring(7);
                File fileCon = new File(rootPath + "/"  + fileName);
                try { 
                    //转换之后文件生成的地址
                    File newFile = new File(rootPath);
                    if (!newFile.exists()) { 
                        newFile.mkdirs();
                    }
                    File file2 = new File(rootPath + "/"+substring+"/");
                    if(!file2.exists()){ 
                        file2.mkdirs();
                    }
    
    
                    String inputFileUrl = rootPath + "/" + fileName;
                    String outputFileUrl = rootPath + "/" + substring + "/" + fileName + ".odt";
                    String inputFileEncode = null;
                    try { 
                        inputFileEncode = EncodingDetect.getJavaEncode(inputFileUrl);
                    } catch (Exception e) { 
                        return "文件内容为空";
                    }
                    BufferedReader bufferedReader = new BufferedReader(
                            new InputStreamReader(new FileInputStream(inputFileUrl), inputFileEncode));
                    BufferedWriter bufferedWriter = new BufferedWriter(
                            new OutputStreamWriter(new FileOutputStream(outputFileUrl), "GBK"));
                    String line;
                    while ((line = bufferedReader.readLine()) != null) { 
                        bufferedWriter.write(line + "\r\n");
                    }
                    bufferedWriter.close();
                    bufferedReader.close();
    
                    File file1 = new File(outputFileUrl);
                    converter.convert(file1).to(new File(rootPath + "/"+substring+"/" + fileName + ".odt.pdf")).execute();
                    //使用response,将pdf文件以流的方式发送的前段
                    ServletOutputStream outputStream = response.getOutputStream();
                    InputStream in = new FileInputStream(new File(rootPath + "/"+substring+"/" + fileName +".odt.pdf"));// 读取文件
    
                    response.setContentType("application/force-download;text/html;charset=ISO8859-1");// 设置强制下载不打开
                    String a = "attachment;filename=" +fileName+ ".pdf";
                    String gbk = new String(a.getBytes("GBK"), "ISO8859-1");
                    response.addHeader("Content-Disposition",gbk);
    
                    DownloadUtils.downLoadFile(response,fileName+ ".pdf",new File(rootPath + "/"+substring+"/" + fileName +".odt.pdf"));
                    in.close();
                    outputStream.close();
                } catch (Exception e) { 
                    e.printStackTrace();
                }
            }
