Currently, when fromCharCode or fromCodePoint is used, the whole string is converted into decimal codepoint even if the string begin or ended with simple characters (numbers, 'N','a','d','e','f','i','l','n','r','s','t','u'). Using "+" to attach those simple characters on head or end of string genetated by fromCharCode can shorten generated code.
