     24     ECMA Section:       15.5.4.4 String.prototype.charAt(pos)
     25     Description:        Returns a string containing the character at position
     26                         pos in the string.  If there is no character at that
     27                         string, the result is the empty string.  The result is
     28                         a string value, not a String object.
     29 
     30                         When the charAt method is called with one argument,
     31                         pos, the following steps are taken:
     32                         1. Call ToString, with this value as its argument
     33                         2. Call ToInteger pos
     34 
     35                         In this test, this is a String, pos is an integer, and
     36                         all pos are in range.
