Because a line feed is not valid in the source code
there.
The unicode escapes are processed by javac when
reading the source, so the error is not specific to
replaceAll.

In this case, bob, the answer was obvious, but in general you should always be specific with your questions. "Why does Java complain?" doesn't say much about the error, i.e., the text of the message, whether it's a compile-time or run-time error, the specific part of the code that had a problem. Just as when you are diagnosing the error yourself, people you ask for help need the details.
That is, if you are sincere about wanting help.
But again, this particular question was simple enough that you got away with it.
