Variations in Summary buffer display

[Stephen Zander <gibreel@pobox.com>]

The following two messages from Shenghuo ZHU came through this list
recently.  When I read them using pgnus 0.31 and Xemacs 20.4 Mule the
'From' lines in the summary display appear differently.  A quick
glance at the headers reveals why, but as they were both sent using
pgnus 0.31 I'm wondering why they vary.  Relevent headers follow.

This one appears as Chinese hieroglyphics:

This one doesn't:

If it makes any difference the first one was a multipart message (it
included a patch).

Perl is really designed more for the guys that will hack Perl at least
20 minutes a day for the rest of their career.  TCL/Python is more a
"20 minutes a week", and VB is probably in that "20 minutes a month"
group. :) -- Randal Schwartz
