Imagine, if roman number is not supported, the sequence
     I J K L M N O P Q R S T...
is generated instead of
     I II III IV V VI VII VIII IX X XI XII...
Is it better than the sequence 1 2 3 4 5 6 7 8 9 10 11 12...?
This simplified example is not so good.  The latin alphabet is small and 
its codepoint order is well known.  But the CJK ideographs are not so --
the sequence &#x4e00; &#x4e01; &#x4e02; &#x4e03;... is nonsense,
1 2 3 4... is much better than the unexpected sequence.
(there are several CJK characters representing "1", not only &#x4e00;)

Unknown numbering sequence should not be "supported", I believe.
