I think I am facing a bug, hope someone (@cketti ?) could point me in the right direction to make a quick patch.
If I receive an E-Mail such as " تست firstname.lastname@example.org" the sender is displayed as “
<Unknown Sender>”. In fact for any E-Mail with non-ascii label (I mean the text before <>), it is displayed as such.
The above email are sent by mailutils in this manner:
mail email@example.com -s "my subject" -a "From: تست <firstname.lastname@example.org>" -a "Content-Type: text/plain; charset: UTF-8" ...
At first I thought it is a problem with Arabic letters, however, the result is the same with other non-ascii letters:
mail email@example.com -s "my subject" -a "From: 蛸 <firstname.lastname@example.org>" -a "Content-Type: text/plain; charset: UTF-8" ...
When I inspect the headers inside K-9, I can see the correct “From” label and address.
Surprisingly, if I send the same thing with Thunderbird it ends up being displayed correctly. I could not find a meaningful difference between E-Mail composed by Thunderbird vs. sendutils.
I tried debugging “MessageListExtractor.kt” in the latest git version and noticed that “cursor.getString” function returns no result for non-ascii mails sent with mailutils.
Would you mind please help me to analyse the problem further and possibly fix it?
Thanks and Merry Christmas
