from the spec: A Unicode character escape sequence represents a Unicode character. Unicode character escape sequences are processed in identifiers (Section 2.4.2), character literals (Section 2.4.4.4), and regular string literals (Section 2.4.4.5). A Unicode character escape is not processed in any other location (for example, to form an operator, punctuator, or keyword).
