Word wrapping in newsgroups on non-plaintext messages

[Martin Peter]

Hi,

i'm trying opera as a newsreader and i'm experiencing some challenges.

I'm reading messages from a private mailing list, that is being
synchronized to a newsserver. Therefore i can compare the same messages in
my emailbox with their counterparts retreived from the newsserver. Here's
the problem:

Most of the messages retr. from the newsserver won't auto-wrap properly on
the end of line (depending on the width of the message window) while the
email messages from the mailinglist wrap properly (both set to "prefer
plain text"). When resizing the newsgroup's message field i can see that
there is a certain autowrap but only if you resize the field wider than
approximatly 105 characters - but not below.

These messages are mostly non-plaintext. Here's is an garbled example
message with header :

Path: news.someserver.com!.POSTED!news01.someserver.com
From: "someone" <som...@news.someserver.com>

some text some text some text some text some text some text some text
some =20
some text some text some text some text some text some text some text
some =20


Why does the same message wrap properly when viewed in my email mailbox
and not when viewed by the build-in newsgroup client?

Is there a way to set the number of characters where line break would be
forced if it isn't possible to set a proper auto-wrap?

I appreciate every attempt to help.

Regards, Martin

This is the important line here. I suspected that the messages were
not being passed as format=flowed, but they are.

I do not know if there is a way to set this, but opera:config might have
something. On the other hand, it is strange that the flowed wrapping
behavior is not the same when reading email messages or news messages.
format=flowed is certainly less common on Usenet than it is in
regular email, but I thought that Opera used the same engine to render
both.

Programming is just another word for the lost art of thinking.

Perhaps the software that converts the email messages into newsgroup
articles, tries to re-format them in some way but doesn't quite get it
right. It would be necessary to see the same message in both forms,
complete with headers, to see where the differences are.

Methinks the private mailing list is at fault: see this bit:

From RFC 2646:

"[Quoted-Printable] encoding SHOULD NOT be used with Format=Flowed
unless absolutely necessary (for example, non-US-ASCII (8-bit)
characters over a strictly 7-bit transport such as unextended SMTP).
In particular, a message SHOULD NOT be encoded in Quoted-Printable
for the sole purpose of protecting the trailing space on flowed lines
unless the body part is cryptographically signed or encrypted (see
Section 4.6).

The intent of Format=Flowed is to allow user agents to generate
flowed text which is non-obnoxious when viewed as pure, raw
Text/Plain (without any decoding); use of Quoted-Printable hinders
this and may cause Format=Flowed to be rejected by end users."
