+  4. If form is not provided or form is undefined, let form be "NFC".
+  5. Let f be ToString(form).
+  6. ReturnIfAbrupt(f).
+  7. If f is not one of "NFC", "NFD", "NFKC", or "NFKD", throw a RangeError
+  exception.
+  8. Let ns be the String value that is the result of normalizing S into the

+  http://www.unicode.org/reports/tr15/tr15-29.html.
+  9. Return ns.
