additions to class String for Unicode normalization

A String object holds and manipulates an arbitrary sequence of bytes,
typically representing characters. String objects may be created using
String::new or as literals.

Because of aliasing issues, users of strings should be aware of the methods
that modify the contents of a String object.  Typically, methods with names
ending in ``!'' modify their receiver, while those without a ``!'' return a
new String.  However, there are exceptions, such as String#[]=.
