public class t {
     [B]//char a = '\u000A'; [/B]
    }

public class t
{
//char a = \u000A;
}

The problem is that those UNICODE character escapes are processed before the
code is parsed.

So to the compiler the code looks like this.

public class t {
     //char a = '
'; 
    }

This is from the Java Language Specification 3.10.4.

Because Unicode escapes are processed very early, it is not correct to write '\u000a' for a character literal whose value is linefeed (LF); the Unicode escape \u000a is transformed into an actual linefeed in translation step 1 (�3.3) and the linefeed becomes a LineTerminator in step 2 (�3.4), and so the character literal is not valid in step 3. Instead, one should use the escape sequence '\n' (�3.10.6). Similarly, it is not correct to write '\u000d' for a character literal whose value is carriage return (CR). Instead, use '\r'.
