Agent and non-ascii newsgroup names

Agent and non-ascii newsgroup names

[Per Abrahamsen]

After CVS updating, I get this message sometimes, either when getting
new news or entering some newsgroups.  

+-------

| However, none of them safely encodes the target text.

| Select one of the following safe coding systems:

Debugging gives me:

The content of  *temp file* is

+------- 
| dk\.test\.utf8-æøå 324 605
+------- 

Which I suspect is the problem.  Agent is trying to save utf-8
information in a Latin-1 environment.

But I have no idea what to do about it.  Suggestions?

It's my error.  I did 

(with-temp-file file-name
  (let ((coding-system-for-write ...))
   ...))

when I should have done

(let ((buffer-file-coding-system ...))
  (with-temp-file file-name
   ...))

With this change, the agent should use raw-text to encode your group
names.  You can get the patch from CVS.

Thanks, it seems to work now.
