The character \u000A is something similar to a new line. In other words, your code gives a compile time error because of the same reason of why the following code is wrong:
The thing to be aware about here is that Unicode escapes such as \u000a are processed as the very first step in the compiler, before the compiler really looks at your code. The Unicode-escaped codes are replaced by their real characters, and \u000a is ofcourse a newline character.
Because of how this works, you cannot use Unicode escapes as a general way to include special characters in your source code (that's not what they are meant for).
