+ 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)
