    File Name:          15.5.4.4-1.js
    ECMA Section:       15.5.4.4 String.prototype.charAt(pos)
    Description:        Returns a string containing the character at position
                        pos in the string.  If there is no character at that
                        string, the result is the empty string.  The result is
                        a string value, not a String object.

                        When the charAt method is called with one argument,
                        pos, the following steps are taken:
                        1. Call ToString, with this value as its argument
                        2. Call ToInteger pos

                        In this test, this is a String, pos is an integer, and
                        all pos are in range.
