    If Character X in HKSCS should map to GB18030 character Y (say Y is in
    the rang of GBK) and
    Character Z in HKSCS shuld map to GB18030 character W (say W is not in
    the range of GBK)
    and you make both Character X and Z in HKSCS map to character Y in GBK
    then later you will find out which Y should be Y in GB18030 and which
    Y should be W in GB18030 ?

    If your conversions is for 'rendering' only, then it probably not a
    big deal, but if you will use it to store persisten data, it may cause
    you nighmare 5 years later.
