[TYPO3-project-seminars] Wrong charset in the body of notification / thank you-mails

[Tobias Schaefer]

Hi,

I installed the TER-version (0.7.3) of seminars for the first time and 
noticed that in the notification / thank you-mails german umlauts were 
missing in the attendees name or in the labels (e.g. Plätze = seats).
It looked like this:

So I downloaded the latest svn-versions (seminars rev. 18817 and oelib 
rev. 18757), copied the files to the server (Suse Linux Enterpise 10) 
and applied the changes to the database in the Extension Manager.
Now the body of the notification / thank you-mails are looking even 
worse, the subject is correct now!

-------------------------------------------

Each paragraph has a "=0D" at the end (which is a carriage return in 
ISO-8859-1) and the german ä is replaced by "=E4". Also the email-header 
(from, content-type, message-id, ...) shoudn't be shown in the body.
I changed plugin.tx_seminars.charsetForEMails to ISO-8859-1 or ISO8859-1 
but it didn't helped.

Does anyone has a solution for this?

Regards,

Tobias Schaefer
