+   File Name:          15.5.3.2-1.js
+   ECMA Section:       15.5.3.2  String.fromCharCode( char0, char1, ... )
+   Description:        Return a string value containing as many characters
+   as the number of arguments.  Each argument specifies
+   one character of the resulting string, with the first
+   argument specifying the first character, and so on,
+   from left to right.  An argument is converted to a
+   character by applying the operation ToUint16_t and
+   regarding the resulting 16bit integeras the Unicode
+   encoding of a character.  If no arguments are supplied,
+   the result is the empty string.
+
+   This test covers Basic Latin (range U+0020 - U+007F)
