improving nnrss.el

[Katsumi Yamaoka <yamaoka@jpl.org>]

Hi,

I and Tsuyoshi AKIHO are now planning to make nnrss.el support
multilingual text.  There was such a demand and a workaround
using the charset group parameter was suggested by the author.

It works only for subjects and text/plain parts by slight
modification of nnrss.el (inserting raw octets into multibyte
buffer breaks them).  Furthermore, to modify mm-view.el so that
it may recognize the charset group parameter will make it work
also for text/html parts.  The troublesome of this way is to set
the group parameter manually.  We are scheming for automating
it, keeping the backward compatibility.  The plan includes
enabling it to use non-ascii group names (i.e., utf-8 encoded).

Regards,
