348921 - Annoying "Message contains characters not found in character encoding" popup when auto save is active

Status: RESOLVED DUPLICATE of bug 328938

(Thunderbird :: Message Compose Window, defect)

Description

[Wolfgang Knauf]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.8.0.5) Gecko/20060719 Firefox/1.5.0.5
Build Identifier:  1.5.0.5 (20060719)

I activated auto save with 1 minute intervals (by the way: really great feature !)

With some mails a messagebox "The message you composed contains characters not found in the selected character encoding ... " pops up. This messagebox comes with every auto save interval, once per minute !
Actually, I do not know why this messagebox comes up. I reply to a mail with ContentType header = "text/plain; charset=iso-8859-1; format=flowed". All characters (also german umlauts) are shown properly in the original message and in my reply. I usually select "Send anyway" (not "Send in UTF-8"), and it seems to work.

I can live with this messagebox if it comes up only when sending the mail. But it is really annoying if it comes up each minute. It would be great if it would not be shown if a message is just saved as a Draft. 

I will attach a screenshot of the messagebox.

My OS is Suse Linux 10.1

Reproducible: Always
