  Some possibilities are given on the following lines.
printStream.printf( "\n" );
printStream.printf( "%n" );
printStream.print(( char )0x000A );
printStream.print(( char )0x000D );
printStream.print(( char )0x000D ); printStream.print(( char )0x000A );
printStream.print(( char )0x0085 ); // 0x0085 is Unicode ?NEL - next line?
printStream.print(( char )0x2028 ); // 0x2028 is Unicode ?line separator?

For a disk file in UTF-8 I can not really see any reason not to use
System.getProperty("line.separator").

If you're trying to get from a Java String to UTF-8 bytes, you could
try using String.getBytes("UTF-8"). The JDK will take care of
converting for you. If your Java String contains \n I'd expect it to
be converted to UTF-8 properly. Once you have the byte array you can
write the bytes directly to the file.

1) \n is line separator on Unix/Linux - it is not line seaprator
on all platforms.

2) \n (and \r) are the same in ASCII, ISO-8859-1, UTF-8 etc..
