Most of Chinese and Chinese-derived character codes are
unified into Unicode area.  Only a few codes can't be
unified with Unicode, and thus decoded into the character
space over #x110000.  But, in that sense, Chinese and
Chinese-derived character codes are not special.  There
exist several non-Chinese character sets (e.g. tibetan)
containing characters that doesn't exist in Unicode, and
they are decoded into the character space over #x110000 too.

But, all of them can be accessed by "\U00XXXXXX".
