decoded authors names in agent/.overview

[Katsumi Yamaoka <yamaoka@jpl.org>]

Hi,

A Japanese user who recently updated Emacs and Gnus into 22.1 and
v5.11 reported[1] that authors' names that appear in summary lines
are broken when reading Japanese newsgroups, e.g., fj.soc.politics.
I also reproduced this problem today only once.  However, it never
arises after I ran `gnus-agent-expire', and I didn't find the way
to reproduce it so far.  In the summary buffer, they looked like:

O  [  29: GON                    ] ...Japanese subject...
O  [   7: Fatman                 ]
O  [  16: ?????? sakaei          ]
O      [  22: ?????? sakaei          ]
O  [   1: ????????????               ]

Those question marks are exactly the ones I saw, though they had
to be Japanese names.  I checked those articles and NOV's in the
nntp server and confirmed they all were correctly RFC2047-encoded
Japanese names.  But I finally found the real cause.  It is that
decoded authors' names were saved in
the ~/News/agant/nntp/SERVER/NEWS/GROUP/NAME/.overview file.  Of
course they are RFC2047-encoded ones normally, though.

Does anyone know what does this, when, how?  Anyway I'm going to
look into it further, next week.
