Hello everyone,

For months I've had a few messages here or there be imported and still show the black diamond with the question mark in place of some german characters. I did a bit more digging and it seems to happen only on nntp articles that don't have "Content-Type" in the header.

Of course it should have that, but if it doesn't it should default to the encoding of the forums, in my case UTF-8. That doesn't appear to be happening.

Something else that seems common to the few I've tracked down is the following in the header:

X-MSMail-Priority: Normal
X-Newsreader: Microsoft Outlook Express 6.00.2900.3598
X-RFC2646: Format=Flowed; Original
X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.3350

Cheers,

James.

It's impossible to verify your claim without looking at the message body. Please upload it or forward to my e-mail address.

I sent it via email. It had someone's personal information in it so I didn't want to make it public without their permission.

It follows the same pattern. I used another few messages to come up with my theory before and the one I sent is another example that follows the pattern.

Let me know if you need anything more...

Cheers,

James.

I've looked at the code (charset_convert() in scripts_common.inc) and I don't think this is going to work. If we convert from X to Y. But if X==Y noting is going to happen.

For example, forum charset is UTF-8; post doesn't specify charset, so we assume it is UTF-8. No conversion is implied.

Any other ideas?

Can we scan the actual text and deduce what the charset is? Somehow Thunderbird displays these messages fine so it must be doing something.

Or how about you look for the Outlook Express signature (not sure if the full Outlook client has the same issue) and then pick the assume that the charset is the windows one and convert from that to charset of forum?

Every case I've seen of this has Outlook Express as the client.

Cheers,

James.

It might work. But it's more than what I'm willing to take on right now. Patches, however, are always welcome.
