HP has offered full KANJI support for quite a number of years.  KANJI is used
in Japan and consist of approximately 30,000-50,000 ideograms.   Rather than
using a keystroke approach as given above (highly impractical), a very special
terminal is employed.  This terminal allows any of the 30K-50K ideograms to 
be entered with a single keystroke.  Note that each character in the KANJI 
languague is represented by 16-bits.
