    ECMA Section:       15.5.3.2  String.fromCharCode( char0, char1, ... )
 
25
    Description:        Return a string value containing as many characters
 
26
                        as the number of arguments.  Each argument specifies
 
27
                        one character of the resulting string, with the first
 
28
                        argument specifying the first character, and so on,
 
29
                        from left to right.  An argument is converted to a
 
30
                        character by applying the operation ToUint16 and
 
31
                        regarding the resulting 16bit integeras the Unicode
 
32
                        encoding of a character.  If no arguments are supplied,
 
33
                        the result is the empty string.
 
34
 
 
35
                        This test covers Basic Latin (range U+0020 - U+007F)
