  I'm afraid not. It seems like the char. is not included in Unicode
3.0. Perhaps, Ext. B or Ext. C has it.

  This works if you know which section a character in question belongs
to, the original CJK ideograph section, Ext. A, Ext. B, Ext. C. Or,
you have to go through all the sections one by one. That's why we have
Han Radical-Stroke Index in section 15.1 of TUS 3.0, isn't it?

  BTW, does Unicode 3.2 have an updated Han Radical-Stroke Index with
Ext. B?
