Handa-san, thank you for the fix in Unicode-2.  I've also made a
change in the Gnus CVS trunk so that it may use a unibyte buffer.
Now it works not only with Emacs 23.0.60 but also with Emacs 22.1,
22.1.50, and 23.0.50.

BTW, I found another problem with Emacs 21 (Gnus still supports
Emacs 21, IIUC).  So, I'll go on looking into it further.

The diff between Gnus trunk and Unicode-2 is here:
