XHTML, Japanese text, non SGML character error message

Ahoy valid folks,

  When the XHTML validator checks a document (a 'forum' page) 
that I am working on it reports error messages for some Japanese text:
"non SGML character 130".

  The validator returns the same error message several times; Each time
it points to a completely different Japanese character.
This does not seem to be correct behaviour.

  I submit this to the mailing list in the hopes that somebody who understands
"SGML characters" and "non-SGML characters" might comment.

  It may be that the document does contain non SGML characters, in which case
I will appreciate a pointer to learn more to help me make the characters so that
they conform to XHTML.  Or it may be a bug in the validator when examining
documents containing Japanese text.
