Problem in printing Chinese characters by using JavaPrintService

Question

Hi, I just develop a tool to print txt files by using Java Print Service.
Everything seems to be good, but when the file contains Chinese character, it can't be print correctly.
I tried to use the DocFlavor.Reader and DocFlavor.STRING, however all of them are failed.
My code is below, please help me, thanks so much
PrintRequestAttributeSet pars = new HashPrintRequestAttributeSet();
// TODO:Printing is not correct because of the Chinese Encoding
DocFlavor flavor = new DocFlavor.INPUT_STREAM("text/plain;charset=UTF-8");//DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
if(defaultService != null){
Iterator<String> it = filename.iterator();
while(it.hasNext()){
shortname = it.next().toString();
abstractPath = GlobalVar.SRC_DIRECTORY_PATH + shortname;
File file = new File(abstractPath);
if(file.exists()){
try{
DocPrintJob job = defaultService.createPrintJob();
FileInputStream fis = new FileInputStream(file);
//BufferedReader br = new BufferedReader(new InputStreamReader(fis,"UTF-8"));
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(fis,flavor,das);
job.print(doc, pars);
}catch(PrintException ex){
Log.doLog("Print failed\t" + shortname, Log.ERROR);
System.out.println(ex.fillInStackTrace());
}else{
Log.doLog("File can't be found: "+abstractPath, Log.ERROR);
}else{
Log.doLog("Can't find printer", Log.ERROR);
}

Everything seems to be good, but when the file contains Chinese character, it can't be print correctly.And how exactly did you determine that the character set in that file is UTF8?
