michael@0:    ECMA Section:       15.5.4.5 String.prototype.charCodeAt(pos)
michael@0:    Description:        Returns a number (a nonnegative integer less than 2^16)
michael@0:    representing the Unicode encoding of the character at
michael@0:    position pos in this string.  If there is no character
michael@0:    at that position, the number is NaN.
michael@0: 
michael@0:    When the charCodeAt method is called with one argument
michael@0:    pos, the following steps are taken:
michael@0:    1. Call ToString, giving it the theis value as its
michael@0:    argument
michael@0:    2. Call ToInteger(pos)
michael@0:    3. Compute the number of characters in result(1).
michael@0:    4. If Result(2) is less than 0 or is not less than
michael@0:    Result(3), return NaN.
michael@0:    5. Return a value of Number type, of positive sign, whose
michael@0:    magnitude is the Unicode encoding of one character
michael@0:    from result 1, namely the characer at position Result
michael@0:    (2), where the first character in Result(1) is
michael@0:    considered to be at position 0.
michael@0: 
michael@0:    Note that the charCodeAt function is intentionally
michael@0:    generic; it does not require that its this value be a
michael@0:    String object.  Therefore it can be transferred to other
michael@0:    kinds of objects for use as a method.
