Newline character in txt file(notepad) displayed as square character

In which operating system are you running the code above?

windows xp

>>appendToFile("blah blah blah \r\n");

Not sure where the above fits in ..?

Are you working on a system other that Windows and then opening the file in Notepad?
Notepad won't deal with non-Windows line feeds - use WordPad instead

Worthwhile attaching (not pasting) the text file in question if you can

I am creating in xp and opening in xp. yes it opens up fine in wordpad.

Isn't there any way to do this such as it will be displyed properly in notepad.

attached.
result.txt

It seems that the file was generated in some unix environment and you are trying opening it on Windows.

If you do this, depending on how the file was transfered, the character "\n" is showed as a square in notepad.

I suspect 'content' has lone newlines ( '\n' ) embedded in it

there was one lone \n instance which has been corrected now. The problem still persists however.

Yes, as i suspected, there are hardcoded newlines in the content. Try the following:

public void appendToFile(String content) {
		try {
			PrintStream outToFile = new PrintStream(new BufferedOutputStream(
						new FileOutputStream(fileHandle.getPath(), true)));
			Scanner in = new Scanner(content);

			while (in.hasNextLine()) {
				outToFile.println(in.nextLine());
			}

			in.close();
			outToFile.close();
		} catch (IOException e) {
			e.printStackTrace();
			throw new RuntimeException("Unable to Write to File");
		}
	}

Add the following line to your code and see what is the default encoding used to write the file and post the result here, please.

System.out.println(System.getProperty("file.encoding"));

Add this line too:

System.out.println(Charset.defaultCharset().displayName());

HI

You need choose the encoding in Notepad as UTF-8, and then try to open it.

Notepad shows special characters if not encoded as UTF-8.

The issue is nothing to do with encoding - it's to do with linefeeds

i removed the /r/n and now it's working. BTW is i don't use println then what line break code should i use. This solution should work for notepad.

depends on what platform you're going to be opening the file
if you're opening it on the same platform that you're java app is running you can use System.getProperty("line.separator")
