Garbage in agent .overview files

Garbage in agent .overview files

[Jesper Harder]

Hi!

I'm seeing strange stuff in some of my agent .overview files -- lots of
control characters, ^H's and ^D's.

Here's an example from .overview:

624	Postscript printers and gsview (78.\b\b.0\b\b\b4.)\b0)	nbeck@weber.ucsd.edu (Nathaniel Beck)	Wed, 8 Aug 2001 18:00:22 +0000 (UTC)	<9krunm$djp$1@news1.ucsd.edu>		1710	43	Xref: defun.localdomain comp.text.tex:624

I get this when I telnet to the server

624	Postscript printers and gsview (4.0)	nbeck@weber.ucsd.edu (Nathaniel Beck)	Wed, 8 Aug 2001 18:00:22 +0000 (UTC)	<9krunm$djp$1@news1.ucsd.edu>		1710	43	Xref: defun.localdomain comp.text.tex:624

Another wierd case is a certain msg-id, 

        <95mqmt0kjhrt8gqo2uqiosonlipsmcqd6d@4ax.com> 

that's garbled every time it appears in .overview, e.g.

But is perfectly normal when I get the NOV lines directly from the
server.

How do you connect to the server?  Anything non-standard like SSL?

No, the server is Leafnode running on my local machine.

Spurios ^H and ^D can be caused by tty interference.  I'm not sure
what to suggest other than using edebug to step through nntp.el and
see where the ^H's are inserted.

I figured out how it happens:  the ^H's are actually there in the output
when I telnet to the server -- but my terminal emulator treats them as
backspace, so I couldn't see them.

So it isn't a Gnus bug.
