     24     ECMA Section:       The String type
     25     Description:
     26 
     27     The String type is the set of all finite ordered sequences of zero or more
     28     Unicode characters. Each character is regarded as occupying a position
     29     within the sequence. These positions are identified by nonnegative
     30     integers. The leftmost character (if any) is at position 0, the next
     31     character (if any) at position 1, and so on. The length of a string is the
     32     number of distinct positions within it. The empty string has length zero
     33     and therefore contains no characters.
