    File Name:          15.5.4.5-3.js
    ECMA Section:       15.5.4.5 String.prototype.charCodeAt(pos)
    Description:        Returns a number (a nonnegative integer less than 2^16)
                        representing the Unicode encoding of the character at
                        position pos in this string.  If there is no character
                        at that position, the number is NaN.

                        When the charCodeAt method is called with one argument
                        pos, the following steps are taken:
                        1. Call ToString, giving it the theis value as its
                           argument
                        2. Call ToInteger(pos)
                        3. Compute the number of characters in result(1).
                        4. If Result(2) is less than 0 or is not less than
                           Result(3), return NaN.
                        5. Return a value of Number type, of positive sign, whose
                           magnitude is the Unicode encoding of one character
                           from result 1, namely the characer at position Result
                           (2), where the first character in Result(1) is
                           considered to be at position 0.

                        Note that the charCodeAt funciton is intentionally
                        generic; it does not require that its this value be a
                        String object.  Therefore it can be transferred to other
                        kinds of objects for use as a method.
