Confusing octal escape sequence

Reports string literals containing an octal escape sequence immediately followed by a digit.

Such strings may be confusing, and are often the result of errors in escape code creation.

Example:

  System.out.println("\1234"); // Octal escape sequence '\123' immediately followed by a digit
