You should not use the Unicode characters \u000a or \u000d. Instead use \n or \r. The reason is that these Unicode values are converted into the actual characters very early in the compile process. Later, when javac breaks your source code into lines and tokens, these characters are treated as actual newline characters and break your statement into 2 lines divided by white space.
Don't use \u000a or \u000d in your source code, use \n or \r. These are the only two cases like that. A Unicode character is \u followed by 1-4 hex digits. Each hex digit is 0-9 or a-f or A-F. They don't all have graphics, certainly not in any one language, but you aren't going to memorize all of them anyway.
Character literals look like: final char A = '\u0041';
String literals can contain Unicode like: final String ABC = "\u0041\u0042\u0043";
