+ 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 function 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.
