  String.fromCodePoint ( ...codePoints )

  1. Let result be the empty String.
  2. For each element next of codePoints, do
    a. Let nextCP be ? ToNumber(next).
    b. If nextCP is not an integral Number, throw a RangeError exception.
    c. If ℝ(nextCP) < 0 or ℝ(nextCP) > 0x10FFFF, throw a RangeError exception.
    d. Set result to the string-concatenation of result and UTF16EncodeCodePoint(ℝ(nextCP)).
  3. Assert: If codePoints is empty, then result is the empty String.
  4. Return result.
