23    File Name:          15.5.3.2-1.js
24    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.

35                        This test covers Basic Latin (range U+0020 - U+007F)
